For this particular model, ClipperLib numerical instability causes
one of the internal surfaces to turn into bridging surfaces
on reslicing. The issue was fixed by reverting to untyped slices if possible.
When propagating overhangs to be supported, the regions are newly
properly merged and regularized.
Fix of Stuck at "preparing infill" with "only infill where needed" enabled 1.41.2 #1696
"Only infill where needed" makes slicer crash for some models #6385
[BUG] Slicing stuck for 14h now, 0.8 NZL Ender 5+ Gyroid infill only where need
first_layer_height cannot be changed to ConfigOptionFloat, that would break loading of old 3MFs.
The relative values from 3MFs should already be converted to absolute in `Preset::normalize`, what is missing is the UI check.
+ Code refactoring for OptionsGroup::create_single_option_line():
Don't clear label value in an Option. This value is used in Field::get_value_by_opt_type() to show error "%s doesn't support percentage".
=> At functions OG_CustomCtrl::CtrlLine::render() and OG_CustomCtrl::CtrlLine::get_pos() added check if current line has more than one option.
=> Draw option's label only when line has several options.

CGAL upstream CMake config will lock in the major version if installed as a distro package and will not provide any version info if compiled and installed from upstream. As of this commit, PrusaSlicer can be built with CGAL 4.13.2, and 5.0 but there is no universal way to specify the minimum version that would work with static dependencies and linux packages.
sorry #4912
1) Areas inside modifier meshes were ironed multiple times.
2) Ironing areas were not properly merged.
Layer::lslices were not always properly merged with modifier meshes
applied, which lead to the ironed surface being split and not fully
ironed, as there were artificial gaps created between regions as if
they were covered by perimeters (we don't iron over perimeters).
Fixes Fan starts at first layer, even though disabled for first layer. #7232
This is a regression due to cooling refactoring, which cooled
support layers independently from object layers. The bug here was that
all the raft layers were cooled together with the first object layer.
Previously, the Cursor (Sphere or Circle) was repeatedly applied between two mouse positions, creating brushstrokes with ripples on the edges between those mouse positions.
Now, a single capsule (3D or 2D) is applied between those mouse positions, which creates brushstrokes without these ripples.
This was a regression of 2.4.0-alpha1 wrt. 2.3.3, where handling of
multiple volumes was refactored.
As a result, handling multi-part objects with clip_multipart_objects
disabled was broken.
With clip_multipart_objects disabled, the multi-part objects no more
clip one another and it is sole responsibility of the user to handle
overlaps.
Fixes "add part" error - PrusaSlicer 2.4.0 b2 #7366
This is a regression wrt. to PrusaSlicer 2.3.3 due to refactoring
of the slicing process for better multi material support
and to support negative volumes.
see pull request #7323 for discussion what went wrong.
The original issue
Fix of Print::apply() creating hierarchy of regions for complex scenarios:
Unnecessary regions were created for a modifier over a volume or a modifier,
where the modifier did not modify any of its parent's properties.
This lead to an explosion of regions for this particular 3MF.
Fixes Non Responsive & Memory Leak when opening or changing this 3MF project #7220
After a0ee41770d
quite often regions were not re-regenerated. This shoul now be fixed
together with the original slowness & memory leak issue.
