--- Comment #10 from Stefan Eßer <[email protected]> ---
A PR with very similar symptoms has been created as bug #265920.

I have not marked either of them as duplicate of the other, since I'm not sure
they are exact duplicates.

An interesting observation in bug #265920 is that DisplayPort is not affected
by this issue, but only DVI.

I have verified that this applies to my card too, but with HDMI failing and
DisplayPort working. (This is not a solution in my case, since another device
is connected to the sole DisplayPort interface of my monitor.)

I do not mark this PR or 265920 as duplicates of each other, since both contain
useful information and the affected graphic cards are different, but I do
assume that fixing the issue in the driver will solve both issues.
