Version: 5.10.13-1
Severity: important
Dear Maintainer,
i encountered weired graphical glitches on my desktop / opened programmes
after one of the last "apt-get dist-upgrade" (KDE / Plasma)
After searching the web maybe same as https://bugzilla.redhat.com/
show_bug.cgi?id=1843274, an screenshot-video of the behaviour can be found at

*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
> Possibly update to one of the latest testing-kernel
* What exactly did you do (or not do) that was effective (or
ineffective)?
> Grub-Option "i915.mitigations=off" seems to work as a workaround, but is
obviously no solution
* What was the outcome of this action?
> No glitches
* What outcome did you expect instead?
