RPCS3 segfaults on exit
Quick summary
RPCS3 seems to segfault when trying to close it. Even when I didn't run any games/software.
Details
Compiled the latest v0.0.28-15141-6d918b56 rev 6f834e99d22e4821b9061aee4e51691de06d2345 on Fedora 38 running the default Gnome 44.1 desktop with Wayland. I'm using an AMD RX 6400 with mesa 23.1.1.
I've compiled RPCS3 with only the "-DBUILD_LLVM=1" cmake flag.
When I open the emulator the GUI appears, but when I close it (by pressing the X in the upper-right corner), the emulator will segfault.

If it doesn't happen with the AppImage, then this is something specific to your environment. Btw, flatpaks are not supported.
I'm not running any flatpaks nor AppImages. I just compiled the vanilla source as per wiki instructions.
This still seems to happen with the latest git as of today. I've deleted ~/.config/rpcs3 and ~/.cache/rpcs3 before running it. I'm running a freshly compiled build through gdb. If there's a better way to debug this please let me know.
But it should be nice to be able to exit the emulator without crashing it.

If I remember correctly this was a Qt Wayland vs NVIDIA bug. It had nothing to do with the emulator itself. I think it should be fixed with the latest 545 driver series and Qt6. Will report back.
