I did a dup from 20210810 to 20210828, and since then I noticed a very slow redraw on KDE Plasma: when scolling in a terminal or in a window, the screen looks 'broken' for a moment, then the rendering is back.

BTW, which kernel was the last working one? Was it already 5.13.x?

Yes, it was 5.13.8. Some Plasma updates flew in between the snapshots as well - but as the Nvidia card seems to work, I would not consider this as the root cause.

Then please try to install again the old 5.13.8 kernel from TW history repo, and confirm that it still works fine, ie. a kernel regression.

I can report it, but I guess I'm lost on any question except 'what hardware are you using?'

Developers would ask you to provide more information with the debug option, etc. There is nothing different from reporting to here. -- You are receiving this mail because: You are on the CC list for the bug.

This is exactly where? (No *history* project on OBS)

Which would be the proper component? gfx-ci? Mesa? xorg?

Tried a dup from the history version, but that causes tons of conflicts *on my workhorse*. So I'm a bit scared. On the other hand, the tests have created so many snapshots that the original 20210810 is gone in between

@tagsys - can you easily return to a working snapshot and give it a try?

unfortunately no, I can't. I switched to nvidia, and bug gone. -- You are receiving this mail because: You are on the CC list for the bug.
