Description richts 2018-07-19 17:32:21 UTC 
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
Comment 1 richts 2018-07-19 17:41:50 UTC 
Just for completeness: I did not have this problem on 4.17.5 (again, the mainline kernel from the ubuntu kernel team)
Comment 2 Michel Dänzer 2018-07-20 07:54:05 UTC 
Please attach the dmesg output and Xorg log file corresponding to the problem.
Comment 3 richts 2018-07-27 14:23:11 UTC 
I didn't forget, it just didn't happen since then...
Comment 4 richts 2018-08-19 06:55:41 UTC 
In the meantime I'm at 4.18.1 and the problem never happened since then.
