Interesting. On Windows I do not get ``` mimalloc: assertion failed: at "/var/tmp/portage/dev-libs/mimalloc-2.1.2/work/mimalloc-2.1.2/src/alloc.c":267, mi_page_usable_size_of assertion: "ok" ``` I also tried on the official 3.1 release - work as well. This...

Even though your mimalloc version is newer the assert is here: https://github.com/microsoft/mimalloc/blob/f819dbb4e4813fab464aee16770f39f11476bfea/src/alloc.c#L231 However on Windows this is not defined: https://github.com/microsoft/mimalloc/blob/f819dbb4e4813fab464aee16770f39f11476bfea/src/alloc.c#L218 so the version without an assert is used: https://github.com/microsoft/mimalloc/blob/f819dbb4e4813fab464aee16770f39f11476bfea/src/alloc.c#L285

But on macOS it seems trackpad vs. normal (two buttons and a click able scroll wheel) vs. Magic mouse (and other Aplle oddities like one button mice) is a bit...

Let's leave this open for now. Removing the invalidate does fix the original problem and I want to look at this carefully on a PC...

Yes, if a particular text in a particular font has overlapping glyphs - either due to kerning or "handwriting" fonts for example - then the sketch will be self intersecting...

I understand. You meant the union of the 2d outlines of the overlapping glyphs. That makes sense. SolveSpace currently does not have this implemented for anything else, so it will...

In principle it is "simple" we already do all of it in 3d. The inside/outside classification I am VERY familiar with ;-) But still it will require some thinking planning...

Here is a much older related issue https://github.com/solvespace/solvespace/issues/285 By the way [SketchFlat](https://cq.cx/sketchflat.pl) could do this:
