[Bug 1219275] New: user interface slow (regression)
https://bugzilla.suse.com/show_bug.cgi?id=1219275 Bug ID: 1219275 Summary: user interface slow (regression) Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: aschnell@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- With the latest kernel-default 6.7.1-1.1 the user interface is slower than before with 6.6.11-1.1. E.g. I can clearly see how windows are redrawn (e.g. content of xterm). I can pinpoint this to the kernel since booting the old kernel resolves the problem.

There has been significant reworks in 6.7. You can try 6.8-rc2 kernel found in IBS Devel:Kernel:master repo. This got a revert in nouveau. I'm not sure whether it's relevant with your problem, but it's worth to try. -- You are receiving this mail because: You are the assignee for the bug.

And if the problem persists with 6.8-rc2, we should report this to the upstream, gitlab issues DRM/nouveau: https://gitlab.freedesktop.org/drm/nouveau/-/issues also report to the linux kernel regression: https://docs.kernel.org/admin-guide/reporting-regressions.html -- You are receiving this mail because: You are the assignee for the bug.

But nouveau received lots of changes since 6.7, and it's hard to say which really fixed your problem; the changes including the significant scheduler changes in nouveau, and that might be the fix in your case. Or it might be the last revert in 6.8-rc2... As an easy try, I backported the patches with Cc-to-stable from 6.8. There were three commits including the revert one I mentioned in the above. The test kernel is being built in OBS home:tiwai:bsc1219275 repo. Could you give it a try later, once after the build finishes? -- You are receiving this mail because: You are the assignee for the bug.

The kernel 6.7.2 from home:tiwai:bsc1219275 also works great.
It's a good news! Then I just need to merge those stable fixes for 6.7. Will work on PR later. -- You are receiving this mail because: You are the assignee for the bug.
