Short description of error
Bizarre graphical errors in EEVEE upon returning from pm-suspend. This occurs whether or not EEVEE is active while suspending; doesn't seem to fix when changing shaders or material settings.

Exact steps for others to reproduce the error
On Ubuntu, install pm-suspend command by:
sudo apt install pm-utils
Run Blender as normal. Suspend the computer by:
sudo pm-suspend
Restore the computer, then enter EEVEE.



Event Timeline

IMO it is better use 430 Nvidia drivers, older one have a bit of problem, i stop to suspend my linux machine with nvidia proprietary drivers, i have always some little problem in KDE on restore from suspension

OK, I'll switch my drivers and try again. Do you think this is a bug in Blender or in Ubuntu?

It has been my experience on Linux that suspend often has trouble restarting graphics and audio. No idea where the problem lies. Your mileage may vary.

This is most likely a bug in the NVIDIA graphics drivers or other part of the graphics stack. There is nothing we do in Blender to handle suspend / restore, it all happens automatically.

You could try reporting the bug to NVIDIA or Ubuntu, but I don't think there is anything we can do about this in Blender itself.
