Comme= nt # 10 on bug 10074= 5 from Dimitrios Liappis 
This is a real problem for me as well, for some time now, with=
 amdgpu (Radeon
RX560), Fedora-27, gnome-shell and Dell P2715Q monitor. It happens both on =
Xorg
and Wayland.

The nuisance here is this almost always crashes gnome-shell. Attached cored=
ump
excerpt.

I used to be able to circumvent the gnome-shell crash by disabling dpms (&q=
uot;xset
-dpms" and/or "xset dpms force off") but this doesn't seem t=
o help anymore.
