https://bugzilla.kernel.org/show_bug.cgi?id=217621 Bug ID: 217621 Summary: AMDGPU - Internal 4K display used with 1920x1080 leads to screen flickering and distortion, regression from commit edcfed8671ee57bb599184f2e12a1b3e11b32306 Product: Drivers Version: 2.5 Hardware: AMD OS: Linux Status: NEW Severity: normal Priority: P3 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: der.timosch@xxxxxxxxx Regression: No Created attachment 304514 --> https://bugzilla.kernel.org/attachment.cgi?id=304514&action=edit Picture showing distorted display I'm on Manjaro, using kernel 6.3 series. The following problem is also reprocucible with 6.1 series (tested 6.1.36) and with NixOS using >=6.3.9. 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 resolution (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: edcfed8671ee57bb599184f2e12a1b3e11b32306. I created a patch to revert the commit and recreated the amdgpu module and everything is fine again. -- You may reply to this email to add a comment.
