https://bugzilla.kernel.org/show_bug.cgi?id=207171 Bug ID: 207171 Summary: [regression][bisected] Ryzen PRO 2400G, firefox screen corruption in X Product: Drivers Version: 2.5 Kernel Version: 5.6.3 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: florian.ziegler@xxxxxxxxx Regression: No Created attachment 288297 --> https://bugzilla.kernel.org/attachment.cgi?id=288297&action=edit dmesg Hello, I have a Ryzen PRO 2400G (HP EliteDesk 705 G4) with kernel 5.6 I am experiencing screen corruption in firefox under X. Symptoms are: - black and white horizontal lines over the whole width of the firefox window - displaced/duplicated renderings all over the screen - black bars over the width of a moving object (sroll-over effect) Only the firefox window is affected. But when I move the window while there are corruptions, the whole screen is affected for 1(?) frame. Windows decorations are not affected. Symptoms vary form website to website, playing video or sites that heavily rerender when scrolling or clicking buttons seems to trigger or increase the symptoms. The symptoms do not appear with weston and firefox. The symptoms do not appear with chromium under X Output of git bisect: # first bad commit: [7af2a5771e0918cdadb1614c1f81dd67a58e00aa] drm/amdgpu: attempt to enable gfxoff on more raven1 boards (v2) If you need pictures or further information, I can provide them. The bug looks similar to this one: https://bugzilla.kernel.org/show_bug.cgi?id=207005 But the reporter claimed that it never worked. My bug report is about a regression. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
