Hello,

if I connect a display over a USB-C docking station on an intel integrated UHD
graphics on a laptop (with a secondary nvidia chip), the display starts to
horribly flicker after a short period of time. Visual glitches, improperly
rendered lines and other things start showing almost immediately after boot,
and after that, the display completely loses signal as well, rendering the
system unusable.

I found out on a lot of forums that this bug is related to new Kernel drivers
from version 5.16 onward, I tested it on an old Debian buster (with kernel
5.14) and everything was fine. The issue however persists from Leap 15.4 to
15.5 to even tumbleweed, which I tried to make sure that newer package versions
wouldn't resolve it.

The docking station model is Dell WD15, however from what I read, it's
completely unrelated to the issue.


If you need more info, don't hesitate to contact me.
