The problem is that is it our bug or a driver bug. I still can't get the bug to happen though, I have 3440x1440 monitor, and I tried with both 150% and 200% scaling, and couldn't notice any issues. It could be a driver bug. Do you get any messages related to the GPU if you have `journalctl -ef` open in a terminal while doing this? Or in `sudo dmesg` ? -- You are receiving this mail because: You are watching all bug changes.
