The editor/project freezes or displays glitched visuals after resuming the PC from suspend

This is a known issue on Linux with NVIDIA graphics when using the proprietary
driver. There is no definitive fix yet, as suspend on Linux + NVIDIA is often
buggy when OpenGL or Vulkan is involved. The Compatibility rendering method
(which uses OpenGL) is generally less prone to suspend-related issues compared
to the Forward+ and Forward Mobile rendering methods (which use Vulkan).
The NVIDIA driver offers an *experimental*
`option to preserve video memory after suspend <https://wiki.archlinux.org/title/NVIDIA/Tips_and_tricks#Preserve_video_memory_after_suspend>`__
which may resolve this issue. This option has been reported to work better with
more recent NVIDIA driver versions.
To avoid losing work, save scenes in the editor before putting the PC to sleep.
The project works when run from the editor, but fails to load some files when running from an exported copy
