When the PC going to full sleep (not hibernation), graphics rendered by GPU2 (Nvidia GeForce GTX 1050) corrupts itself. Most of the time software rendered by GPU2 just crashes, but rarely they remain functional with extreme graphical corruption. But this is only for assets that were already loaded, as new assets will work just fine.

Everything that is instead rendered by GPU1 (Intel UHD Graphics 630) is not affected.
KDE Plasma (X11) is not affected.

Ive had this many years ago. It was Nvidia drivers.
I dont remember the fix unfortunately. I fixed it somehow.
