Describe the bug

With a high GPU load, sometimes Wayfire suddenly ends the session. It's quite difficult to track the exact cause, but it always happens under high (and even medium) GPU load, for example: Minecraft with shaders, render in Blender.

Wayfire crashes precisely when the GPU is under load.
Wayfire crashes suddenly, then, after few seconds, SDDM shows.

This is very annoying because playing games turns into Russian roulette, and rendering projects at work turns into a nightmare.

I suspect it's something like a malloc error (returns NULL pointer and use it after that, although stable systems should handle the returned NULL pointers without crash and using NULL pointers) when there is not enough video memory or something like that, but I don't know for sure.

What to do?

Should I try to start rendering in Blender when Wayfire is running with debug? But which flags should I use? Something like this? WAYLAND_DEBUG=1 WAYFIRE_DEBUG=1 wayfire 2> wayfire.log

No source file, test, or entry point is named. Start by reproducing the crash with Minecraft shaders or a Blender render while collecting the proposed Wayfire log and GPU details; done means identifying a reproducible cause and documenting a verified fix or diagnostic result.
