            Bug ID: 200605
           Summary: Screen flickering on AMD graphics in 4.18
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.18-rc5
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: richts@gmx.at
        Regression: No

I'm using the ubuntu kernel team's 4.18-rc5 build and I sometimes experience
regions flickering (black) until they get fully refreshed (not sure, but this
seems to happen after resuming). I have no special kernel options set.

Graphics card: RV710/M92 [Mobility Radeon HD 4530/4570/545v]

Kernel: 4.18.0-041800rc5-generic #201807152130 SMP Sun Jul 15 21:32:10 UTC 2018
x86_64 x86_64 x86_64 GNU/Linux

Just for completeness: I did not have this problem on 4.17.5 (again, the
mainline kernel from the ubuntu kernel team)
