I just checked 1.0.2: https://github.com/FreeCAD/FreeCAD/blob/1.0.2/src/Gui/Application.cpp#L2260-L2275
Turns out that patch is not (yet) picked to that release branch. So while #431206 will conflict with this PR in git, this indeed looks like the correct (long-ish) term fix. Thank you for looking into this! I'll do one last build and test, but looking good.

25.05 doesn't have coin 4.0.4+ yet. If it does update, we'll need to backport this fix. If it had applied cleanly, i'd have just done it - it doesn't hurt on older coin3d. However, seeing as it would need a manual backport, i'll not bother for now until the coin backport is drafted.

@LordGrimmauld
Im still having rendering issues with this branch

couple notes:

• the video doesn't play for me
• this was never meant to fix rendering issues. The issue fixed here was a hard crash.
• Rendering issues are a new bug. Open a dedicated issue report for that and i can maybe take a look. Be aware though rendering issues can be hardware/driver dependent, it is often not trivial to reproduce those.
