[Bug 1944951] Re: KDE delayed display update / konsole artifacts

[andik]

Maybe this helps:

I'm using a somewhat newer version of the Intel VGA:

00:02.0 VGA compatible controller: Intel Corporation CometLake-S GT2 [UHD Graphics 630] (rev 03)
and I do not have an additional Nvidia card.

Switching from modesetting_drv.so to intel_drv.so also causes the
problem is disappear, but the Intel driver sometimes produces annoying
screen flickering.
