Bug#996676: plasma-workspace: Plasma flickering with Intel chipset.
Package: plasma-workspace
Version: 4:5.20.5-6
Severity: important
X-Debbugs-Cc: m@pierre-parent.fr
Dear Maintainer,
I recently updated to debian 11, since then appeared a flickering on plasma-
workspace elements.
For exemple the bottom task bar, and all kde elements, flicker when interacting
with them. The
flickering does not occur within the windows themselevse, or the desktop
effects.
You can get an overview of the problem here:

I've tried to play with /etc/X11/xorg.conf.d/20-intel.conf without any succes.
No configuration
could get rid of this problem (including removing the file itself as done by
default).
I've tried all posible compositor configuration without any success.
I've reseted my plasma configuration without any effect.
Here is the reference of my graphic card:
VGA compatible controller: Intel Corporation CometLake-U GT2 [UHD Graphics]

Thank's a lot!
