The following problem is also reprocucible with 6.1 series (tested 6.1.36) and with NixOS using >=3D6.3.9. I usually use my internal display and an external display with 3840x2160 and 100% scaling. I use my internal display not in its native 3840x2160 resolut= ion (and 200% scaling), but with 1920x1080 and 100% scaling, to prevent scaling issues under Gnome when moving windows from one display to the other. That worked until I updated from 6.3.8 to 6.3.9 (and lately 6.3.10). I suspected= the following commit to be responsible: edcfed8671ee57bb599184f2e12a1b3e11b3230= 6. I created a patch to revert the commit and recreated the amdgpu module and everything is fine again. --=20 You may reply to this email to add a comment.
