[BUG] Crash when launching any game on citron/eden (and likely all yuzu forks) on x11.

[Samueru-sama]

Trying lsfg-vk on citron or eden causes it to crash when trying to load any game. vkcube works perfectly I was also able to launch BeamNG drive although this one has a separate issue of terrible performance.

• Launched with: ENABLE_LSFG=1 LSFG_MULTIPLIER=2

• Starting any game causes this error: lsfg-vk(hooks): Encountered Vulkan error 0 while creating swapchain context: Failed to allocate memory for Vulkan image (error 0)

• Finally it crashes with:

terminate called after throwing an instance of 'std::out_of_range'
  what():  unordered_map::at

• The emulators do not crash when I force them to use wayland thru a compatibility layer 12to11, in that case it works perfectly.

System information

• Artix Linux 6.15.2-artix1-1 - i3wm
• The same errors also happen on the Steamdeck.

I can confirm the same error with every yuzu fork emulator on steamdeck using x11.
switch steamdeck desktop mode to wayland will not crash, but fps will be so low.

super weird... there's not really anything I cam conclude from these logs. I guess it's a good thing to see the same issues pop up rather than new ones, but I really don't know how to fix em.

Hello, please re-report these issues with all their log files on the discord. It'll be much easier for me to take a look at them that way.
