I close my laptop, and it went suspend and after I arise it, I found that the wallpaper of my 3rd virtual desktop replaced with black and white squares. I thought that may result from Nvidia card. Reproducible: Sometimes Steps to Reproduce: 1.suspend your laptop 2.arise it 3.check wallpaper Actual Results: If it happens, you could find desktop replaces by white and black squares.
Created attachment 90334 [details] This is the result
Does it change back to sane when you suspend the compositor (Shift+Alt+F12)?
could you please provide the output of: qdbus org.kde.KWin /KWin supportInformation
