I can confirm that this patch fix the issue.

But I did not like one thing:
I decided to check how work VEGA GPU through HDMI and connected the second
monitor via HDMI.

The first that I did not like was that on the first monitor which was connected
via DisplayPort, the scaling setting was reset from 200% to 100%.

The second that I did not like was that when I tried to set the scaling at 200%
through gnome-settings, my computer was hung. I even could not connect through
ssh to look at the kernel log.

I tried to repeat this case but unsuccessfully, but unpleasant residue still
remained.
