The only text corruption I've seen as yet is a little bit of horizontal lines for a second or two after selecting some text in Konsole, then selecting edit > copy from the menu bar. It is repeatable. The corruption is approximately limited to the area defined by the edit > copy menu space. Other corruption I found was in system settings > compositor, which on first mouseover the content area the various fields overlaid each other until I forced a redraw, but the text in the fields was normal where not hidden by overlay. This too is repeatable by closing systemsettings5 before trying again. -- You are receiving this mail because: You are on the CC list for the bug.

Just upgraded from openSUSE 20211008 to 20211031, which included an update from kernel-default 5.14.9 to 5.14.14. The problem is now worse: the glitches appear even when the compositor is enabled.

Booting from the old 5.14.9 kernel doesn't work around the glitching problem, but booting from the old read-only snapshot does. Also, I've found that the glitching can be avoided by running a Wayland desktop instead of X11. (In reply to Takashi Iwai from comment #3)

Dup of bug 1190095?

I'm not sure; the symptoms reported are similar but still different. Bug 1190095 talks about a "slow redraw" where the screen glitches for a moment and then fixes itself. But in my case, I wouldn't say that the redraw is "slow"; the glitches appear instantaneously when a screen area changes (e.g., via scrolling), and they generally persist until I force that area of the screen to change again, at which point the glitching either changes or (if I'm lucky) disappears. -- You are receiving this mail because: You are on the CC list for the bug.
