Created attachment 135670 [details] Quern crash - bt full Quern crashes before showing the main menu. Same happens with "Unturned" game, with pretty much identical stack.

Looks like there might be memory corruption, can you run one of these games in valgrind and attach the output from valgrind?

(In reply to Michel Dänzer from comment #2) > Looks like there might be memory corruption, can you run one of these games > in valgrind and attach the output from valgrind? Valgrind output attached. Looks quite useless to me... Interestingly, Quern actually shows the main menu when run under valgrind. A duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=101675 then?
The valgrind output for Quern shows writes to freed memory, because the game makes libX11 calls using a display handle that it had already closed. That's a bug in the game (or maybe in a library it links statically), which could explain the crash. I don't see any obvious issue in the valgrind output for Unturned either though.
Both games use the Unity engine. Marking this as duplicate of 103769. *** This bug has been marked as a duplicate of bug 103769 ***
