Resolved 4 conflicts:
- PrintConfig.hpp / Preset.cpp: upstream restored calib_flowrate_topinfill_special_order
(removed in the prior merge, now re-added and re-registered); kept it alongside our
IMEX options (imex_parallel_mode, imex_head_filament_map).
- Plater.cpp: kept our <sstream> include plus upstream's <optional> and plugin includes.
- tests/fff_print/test_gcodewriter.cpp: both sides appended disjoint scenarios after a
shared base. Reconstructed as upstream's full file (base + its 3 toolchange/H2C
scenarios + the boost/filesystem include its helper needs) followed by our 10
set_pressure_advance / set_temperature scenarios. 22 scenarios total, no duplicates.
Resolve five conflicts, all of which needed both sides rather than a pick:
- BackgroundSlicingProcess: ours was a pure tabs->spaces reformat of base, so
keep main's per-filament volume/nozzle map read-back (its only change here).
- GUI_App: main's #12506 else-if attached to an `if` this branch deleted;
re-expressed onto the same-agent early-return path (the agent factory caches
per id, so pointer equality is the same predicate).
- MainFrame: both sides relocated Sync Presets independently; keep main's
push_notification plus the branch's Plugins menu items.
- Tab: the "TODO: Orca: Support hybrid" blocks were unchanged base, not a branch
decision; take main's enabled Hybrid to match the already auto-merged siblings.
- test_config: union of both sides' cases (6 plugin + 9 multi-nozzle).
Conflicts were all co-located additions rather than design collisions:
- GCode.cpp: adopt upstream's toolchange(filament_id, nozzle_id) signature and
per-variant set_config_index() while keeping the IMEX bare-T<n> suppression;
rebase the second-layer temperature loop's non-IMEX branch onto upstream's
get_filament_config_index() resolution.
- Preset.cpp / PresetBundle.cpp / PrintConfig.cpp: keep both sides' option-list
and enum-map entries.
- GLCanvas3D.cpp: upstream's printable_heights argument plus the IMEX ghost pass.
- PartPlate.cpp: keep <set> (still used).
- test_gcodewriter.cpp / test_3mf.cpp: keep both sides' test cases.
Resolves two conflicts:
- GLCanvas3D.hpp: keep both the IMEX ghost render declarations and
upstream's _render_wireframe_overlay().
- test_gcodewriter.cpp: both sides appended test cases to the same
region; keep upstream's origin/machine-limit tests alongside the
pressure-advance and temperature scenarios.
Plater's pImpl (unique_ptr<priv> p) is destroyed before the wxWindow base
destructor runs DestroyChildren(), so child GLCanvas3D windows are torn down
after p is gone. GLCanvas3D::~GLCanvas3D() -> reset_volumes() then dereferences
the freed p through two paths:
- Selection::clear() -> plater()->canvas3D() -> p->get_current_canvas3D()
- _set_warning_notification() -> plater()->get_notification_manager()
Guard both with the existing wxGetApp().is_closing() flag; both are UI-only
side effects that are no-ops during shutdown, so normal-use behavior is
unchanged.

Multi-nozzle sync widget, AMS rack-nozzle mapping popup, calibration rework, send-dialog nozzle mapping and extruder-count UI. Includes the fix to persist the AMS sync badge on filament cards (H2C/A2L and direct-sync printers).
Catches the iXex/IDEX parallel-printing branch up to upstream main
(102 commits). Two content conflicts resolved:
- src/libslic3r/Preset.cpp: s_Preset_printer_options — kept upstream's
new "use_3mf" key and our iMEX printer-capability/mode keys.
- tests/fff_print/test_gcodewriter.cpp: upstream revived the disabled
suite (#14196), dropping the obsolete [.]-tagged lift() test and its
config_lift_unlift.ini; kept their set_speed + z_hop tests and appended
our 10 per-firmware set_pressure_advance/set_temperature scenarios.

_render_imex_ghosts and _picking_pass_imex_ghosts both walked every
plate in the partplate list and rendered/hit-tested all ghosts found —
which meant background plates' ghosts bled through into the active
scene whenever GL state was shared (most visibly when entering paint
mode), and clicks could land on a ghost that belonged to a plate the
user wasn't actually looking at.
Switch both paths to read get_curr_plate() and skip the per-plate loop.
Per-plate ghost volumes still live on each PartPlate so 3MF
round-trips work and switching plates picks up the new active plate's
ghosts cleanly; we just don't draw or hit-test the ones whose plate
isn't the active one.

Felix14-v2 PR review feedback (https://github.com/OrcaSlicer/OrcaSlicer/pull/13086#issuecomment-4323696312)
plus the slice-time validation work that follows from his bug list.
UI polish:
- Capitalize "Primary" in display (right-click mode menu, plate tooltip).
Sentinel stays lowercase for wire compatibility.
- Pre-slice-warnings checkbox now uses Orca's ::CheckBox so it matches the
green toggle style of the rest of the IDEX/IQEX configuration page.
- DPI-scaled the IMEXModesCtrl (modes editor) sub-panels, button grid,
text wraps, gcode textarea, and the ghost-tooltip swatch (imgui.scaled).
Legend swatches sized to body-text height for visual balance.
- Primary mode tool buttons in the modes editor are now disabled (read-
only): cycling roles on the IMEX-off mode is a no-op and confusing.
- Modes editor sub-panels now explicitly inherit the app's window-default
dark colour so chromeless ScalableButtons don't render with a visible
light box around their icons on GTK dark themes.
- Per-mode-line reset arrows in the modes editor: each row gets a small
reset bitmap that snaps that row's name+tools+gcode triplet back to the
saved preset's value. matches_config() guard on the page-level reload
prevents the textbox-being-typed-into from being destroyed mid-keystroke.
- New View menu item "Show IDEX/IQEX Toolhead" — toggles the per-carriage
footprint boxes during G-code preview playback. Gated to Preview tab +
IMEX printer; backed by app_config so it persists.
Coordinated config migrations:
- imex_tool_layout and imex_viz_theme migrate from coString to coEnum
(ImexToolLayout / ImexVizTheme). Existing wire format preserved so
saved presets and 3MFs deserialize unchanged. Side-benefit: both now
pick up standard Field rendering and so finally show reset arrows.
Slice-time safeguards (the validation half):
- imex_suppresses_bare_toolchange(parallel_mode, count): suppresses the
slicer's bare T<n> at print-start in any IMEX parallel mode (the user's
imex_mode_gcode + machine_start_gcode owns tool activation there). Mid-
print T<n> emits normally — Print::validate blocks the configurations
where mid-print T<n> wouldn't make sense. Applied to both code paths
inside GCode::set_extruder (the long multi-extruder path AND the
single-extruder path that fires when multiple_extruders=false).
- imex_multicolor_block_reason(): hard-stop validator returning a user-
facing reason string when the active IMEX configuration can't physically
support multi-color. Catches IDEX (1 tool/gantry), 2-tool-active IQEX
(no within-gantry swap topology), and any MMU/AFC lane sharing among
used filaments. Wired into Print::validate as a slice blocker, and into
PartPlate::has_imex_multimaterial_conflict so the plater badge agrees
with the slice block (no more false positives where the badge warns but
the slice goes through).
- New imex_mode_types config option (parallel array to imex_mode_names)
and imex_mode_type_for() helper. Mode-type tag drives behaviour: zones,
ghosts, and validation interpret modes differently per type. Initial
types: "primary", "copy", "mirror", "split". Split modes are explicitly
designed for paired-gantry IQEX multi-color and bypass the gantry-pair
check in imex_multicolor_block_reason (MMU sharing still blocks them).
Test coverage:
- New unit tests cover imex_suppresses_bare_toolchange (4 cases),
imex_multicolor_block_reason (8 cases including IDEX, IQEX 2-/4-tool-
active, MMU sharing, missing primary, Split type), and imex_mode_type_for
(3 cases including legacy fallback). Total: 186 IMEX assertions across
71 test cases, all passing.

* Fix: Enable instance collision detection in GCode and Print clearance
Squashed commit containing:
- Fix gcode path conflict detection in ConflictChecker.cpp by iterating all instances.
- Improve clearance validation in Print.cpp by calculating convex hulls per instance (fixes scaling/mirroring issues).
- Added // Orca: comments to mark changes.
* Fix Wipe Tower G-code conflict detection for WipeTower2
* Fix: Improve object/instance selection for collision and validation warnings
- Updated validation logic in Print.cpp to report specific ModelInstance instead of ModelObject for collision/clearance warnings.
- Updated NotificationManager and Plater to handle ModelInstance selection in 'Jump to' links.
- Added fallback to object selection if specific instance cannot be selected.
- Included fixes for G-code conflict detection (ConflictChecker, GLCanvas3D) to also report instances.
- Improved GUI_ObjectList to update canvas selection when items are selected via API.
* Fix: Prevent crash when loading .3mf projects
Moved update_selections_on_canvas() out of ObjectList::select_items() to avoid premature UI updates during loading. Canvas updates are now explicitly called in NotificationManager and Plater callbacks where needed.
* Fix: Address code review comments
- Fix memory allocation for extrusion layers deep copy
- Remove unused variable in GLCanvas3D
- Fix string formatting crash risk in NotificationManager
- Remove dead code in Plater

refactors tooltipbutton,
one common implementation,
one common shortcut data structure,
add tooltip button to text gizmo,
consistent shortcut wording
Co-authored-by: Hanno Witzleb <hannowitzleb@gmail.com>
_picking_pass_imex_ghosts is what resets m_hover_ghost_head, but _picking_pass
early-returns (mouse drag, mouse off-canvas, gizmo drag) skip that reset. If
the user switches from an IMEX printer to a non-IMEX one during such a window
the plate clears its ghost volumes while the stale head index survives,
producing an orphan tooltip anchored to nothing.
Validate the hover state against live ghost volumes before rendering the
tooltip and self-heal the indices when they no longer point at anything.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Replaces the plater-icon popover with colored transparent ghost copies
of primary-head instances on the plate, one per secondary active head
under its Copy/Mirror role transform. Left-click on a ghost opens a
compact filament picker popover for the ghost's head (MMU lane override).
Ghosts track the primary through drag/rotate/scale/mirror and invalidate
on mode or pem changes.
Key pieces:
IMEXHelpers -- imex_head_transform (Primary/Copy/Mirror), shared role
parser, per-head filament resolution with X-axis Mirror anchor.
PartPlate -- ghost state, volume rebuild on mode/map/object mutation,
primary_origin plumbed for Mirror reflection across the primary-row
gantry plane.
GLCanvas3D -- ghost rendering with per-head filament color and
translucent blending; picking routed via volume composite id.
Plater -- ghost click + tooltip; plater icon left-click always cycles.
IMEXFilamentPickerPopover -- BitmapComboBox row for one secondary head,
writes imex_head_filament_map on selection.
bbs_3mf -- round-trip the per-plate imex_head_filament_map option.
PrintConfig -- add imex_head_filament_map as a plate option.
MMU/AFC routing for parallel modes relies on the printer profile's
physical_extruder_map (see prior commit for authoring format). Primary-
row heads and their per-plate filament overrides are resolved through
that map, so PA and temperature emission address the correct physical
extruder when multiple logical slots share one carriage.
Tests: IMEXHelpers coverage for Primary/Copy/Mirror transforms
including a 2x2 off-row regression guard for the X-axis reflection fix.

* Add runtime display backend detection for Wayland support
Add LinuxDisplayBackend utility to detect X11 vs Wayland at runtime
using GDK_IS_X11_DISPLAY / GDK_IS_WAYLAND_DISPLAY macros. This is
the foundation for removing the forced GDK_BACKEND=x11 and enabling
native Wayland support.
- New files: LinuxDisplayBackend.hpp/.cpp with get_linux_display_backend(),
is_running_on_wayland(), and is_running_on_x11()
- Propagate wxHAVE_GDK_X11 / wxHAVE_GDK_WAYLAND from FindGTK3.cmake
as compile definitions to libslic3r_gui
- No-op on non-Linux platforms (returns Unknown / false)
* Fix Phase 1 code quality: pragma once, source ordering, static cache
* Make X11 initialization conditional for Wayland support
Remove the unconditional GDK_BACKEND=x11 force that blocked native
Wayland. Replace with conditional logic:
- EGL safety fallback: re-force X11 only when wxUSE_GLCANVAS_EGL is
off and WAYLAND_DISPLAY is set, with a warning log
- XInitThreads() only called when DISPLAY is set (X11 in use)
- __GLX_VENDOR_LIBRARY_NAME only set when DISPLAY is present (GLX-specific)
- WEBKIT_DISABLE_COMPOSITING_MODE only set under XWayland (both
DISPLAY and WAYLAND_DISPLAY present)
- Guard X11/Xlib.h include with __has_include for robustness
- Restore display validation to accept either DISPLAY or WAYLAND_DISPLAY
This is Phase 2 of the Wayland support plan.
* Fix Phase 2: safer EGL macro check, add clarifying comments
* Add GLAD2 library and replace GLEW linkage in build system
Set up GLAD2 as a static library to replace GLEW for OpenGL loading.
GLAD2 supports both GLX and EGL, which is required for Wayland support.
- Create src/glad/ with pre-generated GLAD2 sources (GL 4.6 compat)
- Add src/glad/CMakeLists.txt building glad as a static library
- Wire glad into src/CMakeLists.txt before libvgcode
- Modify libvgcode to use shared glad for GL path (keeps local copy
only for GLES2/Emscripten) to avoid duplicate symbol conflicts
- Replace GLEW::GLEW with glad in libslic3r_gui link libraries
Note: GLEW is kept in deps for OpenCSG. Code migration from GL/glew.h
to glad/gl.h headers will follow in Phase 3B+3C.
* Fix Phase 3A+3D: libvgcode GLAD include, dead files, dlopen dep, OpenGL link var
* Migrate from GLEW to GLAD: replace headers and API calls across codebase
Replace all #include <GL/glew.h> with <glad/gl.h> across 49 source files.
Migrate GLEW API calls to GLAD equivalents:
- glewInit/glewExperimental -> gladLoaderLoadGL()
- GLEW_EXT_* / GLEW_ARB_* extension checks -> GLAD_GL_EXT_* / GLAD_GL_ARB_*
- Remove GLEW-specific EGL/GLX mismatch #error guards (not needed with GLAD)
- Replace unavailable EXT symbols with core GL equivalents in
GLCanvas3D.cpp (GL_MAX_SAMPLES, glRenderbufferStorageMultisample,
glBlitFramebuffer, GL_READ/DRAW_FRAMEBUFFER)
- Update log messages from glewInit to gladLoadGL
* Fix Phase 3B+3C: remove GLEW find, clean EXT symbols, update attribution
- Remove find_package(GLEW) block from root CMakeLists.txt since GLEW
is no longer linked by any main application code
- Remove "glew" from SLIC3R_STATIC option description
- Replace all remaining EXT framebuffer symbols with core equivalents
in render_thumbnail_framebuffer_ext and _rectangular_selection_picking_pass
- Update AboutDialog credits from GLEW to GLAD
* Enable EGL in wxWidgets and add runtime GLX/EGL selection for Wayland
- Set wxUSE_GLCANVAS_EGL=ON in wxWidgets build and Flatpak manifest
- Add PreferGLX() call on X11 sessions for driver compatibility
- Remove Phase 2 safety fallback (EGL is now always compiled in)
- Guard SwapBuffers against hidden canvases to prevent Wayland stalls
* Fix Phase 4: move PreferGLX to app startup, fix FPS counter guard
Move wxGLCanvas::PreferGLX() from OpenGLManager::create_wxglcanvas()
(static initializer) to GUI_App::on_init_inner() before any wxGLCanvas
is constructed. This prevents a race where SkipPartCanvas could trigger
wxGLBackend::Init() before the GLX preference is set. The new location
also adds explicit is_running_on_wayland() detection with a warning for
unknown backends.
Move increment_fps_counter() inside the IsShownOnScreen() guard so FPS
is only counted when a frame is actually swapped.
* Update GLFW from 3.3.7 to 3.4 for runtime Wayland/X11 backend selection
Replace the compile-time GLFW_USE_WAYLAND flag (which locked to a single
backend) with GLFW 3.4's GLFW_BUILD_WAYLAND + GLFW_BUILD_X11 flags that
build both backends and auto-select at runtime based on the available
display server. This enables the CLI thumbnail renderer to work on both
Wayland and X11 sessions without separate builds.
* wayland: Fix UI call sites that rely on global screen coordinates
On Wayland, wxGetMousePosition() returns (0,0) and SetPosition() is a
no-op for top-level windows. Fix the highest-impact call sites:
- GLCanvas3D: Use cached m_mouse.position from event handlers instead
of wxGetMousePosition() + ScreenToClient() in get_local_mouse_position()
- Plater: Use event-relative coords via ClientToScreen(e.GetPosition())
instead of wxGetMousePosition() in 3 leave-window handlers
- BBLTopbar: Use event.GetPosition() and FindToolByPosition() directly
in mouse handlers instead of wxGetMousePosition()/FindToolByCurrentPosition()
- Search: Use focus-based dismiss logic on Wayland instead of
wxGetMousePosition()-based rect checks in SearchDialog and
SearchObjectDialog
- GUI_App: Skip SetPosition() in window_pos_restore() on Wayland where
it is a no-op; still restore size and maximize state
- Button: Position tooltip relative to button widget via ClientToScreen
instead of wxGetMousePosition()
* Fix SearchDialog Wayland dismiss: guard against search_line focus
* flatpak: Add Wayland socket permission for native Wayland support
* spec
* Fix crash on Wayland when wxWidgets lacks EGL support
Restore the safety fallback that forces GDK_BACKEND=x11 when wxWidgets
was not built with wxUSE_GLCANVAS_EGL=ON. Without this, the GLX backend
tries to access a non-existent X11 display on native Wayland, crashing
in wxGLCanvas::IsDisplaySupported() with SIGSEGV at offset 0xe4.
Also add a defense-in-depth guard in detect_multisample() that skips
the IsDisplaySupported call entirely on Wayland without EGL.
Root cause: deps/wxWidgets must be rebuilt after enabling EGL. The
compile-time check in OrcaSlicer.cpp detects the mismatch and falls
back safely.
* Fix EGL detection: use wxHAS_EGL instead of wxUSE_GLCANVAS_EGL
wxUSE_GLCANVAS_EGL is a CMake build option, NOT a C++ preprocessor
macro. The actual macro defined in wxWidgets setup.h is wxHAS_EGL.
All compile-time EGL checks were using the wrong macro, causing
the safety fallback to always trigger even with a properly built
EGL-enabled wxWidgets.
* Fix GL function pointers invalidated on Wayland/EGL
gladLoaderLoadGL() dlopen's libGL.so.1 to resolve GL function pointers
via dlsym, then immediately dlclose's the handle. On X11/GLX this is
fine because the GLX context keeps libGL.so mapped. On Wayland/EGL,
nothing else holds libGL.so open, so dlclose unmaps it and all function
pointers become dangling — causing SIGSEGV on the first GL call.
Fix: on Wayland, use gladLoadGL(eglGetProcAddress) which resolves
function pointers through the EGL loader without opening/closing
libGL.so.

* fix crash on close
* small refactor
* move GPU selection to desktop file
* clean up a bit
