Hi!

Since I've installed Fedora 22 (3 months ago), I've got this yellow/blue line
of noise on the right side of my display. This bug arrives mostly when resuming
a session (for instance if I went AFK for an hour, got back and move the
mouse). When I take a screenshot, the problem doesn't appear, but here is a
photo taken with my cellphone:

I'd say that 90% of the times I "wake up" my machine, I've got this bug. I
didn't have that on Manjaro before.

I have a Radeon HD 6870 with a BenQ GW2765 display (2560x1440), running the
open source drivers, of course.

I don't know what log file to give that would be interesting for you. But
please ask if you need one.

Cheers!
