--- Comment #13 from Alex Tucker <a...@floop.org.uk> --- I finally managed to reproduce the bug, after paring down my system to just the AMD GPU I was originally using ("APU" 5700G CPU with GPU) and restricting the VRAM in the BIOS to 1GB. I believe it was 4GB when I originally posted this report, but wanted to see whether I could reproduce the bug more quickly by reducing the available VRAM. I'm running with two monitors, three virtual desktops and two separate activities (for home and for work). As far as I can tell, the bug more often happens after resuming from suspend. I'll now try with KWIN_USE_BUFFER_AGE=0. I've added this to .config/plasma-workspace/env/kwin.sh with the following contents: KWIN_USE_BUFFER_AGE=0 export KWIN_USE_BUFFER_AGE -- You are receiving this mail because: You are watching all bug changes.
