Comment= # 9 on bug 96868<= /a> from iuno@posteo.net 
I have the same problem with my Hawaii card and my WQHD 144 Hz=
 monitor. It is
not X related and the effect is visible on the framebuffer console, too.

120 Hz setting does flicker like seen in comment 7.
144 Hz setting has a flickering vertical bar a few pixels wide on the left
side, a vertical bar in the center of the screen and overall blurred image.

The OSD of the monitor shows that the input is 2568 pixels wide, has a 214 =
KHz
horizontal and 139 Hz vertical refresh rate. When using with Intel GPU (whi=
ch
works correctly) it shows 2560 px, 222 KHz and 144 Hz.

Tried both radeon (linux 4.7.6) and amdgpu (linux 4.8)
