I have a system76 laptop (Oryxp3) which works flawlessly with Kubuntu, hibernation and suspension too, drivers and everything too (battery sucks, but it's mostly a software problem which will take a lot of time to address), but for whatever reason only the DESKTOP makes some weird glitches when resuming from suspension/hibernation.
I can fix it by changing Layout from "Folder view" to "Desktop", applying and then reverting back to "Folder view", so it seems like a refresh problem.
Although I would love to have either a proper fix to refresh my desktop after suspend, or a command to do that. A hack or a workaround that I can bind to a command, I'm just too lazy to unlock widgets, right click, change option, apply, revert, apply every restore from suspension.
My GPU is NVIDIA GTX 1070 with NVIDIA drivers: 375.39
Here is how it looks, although sometimes is worse and the font gets all colored in weird ways and it's unreadable:
