I have the same issue with Radeon R9 290. In addition to those horizontal stripes glitches, video codecs don't work properly and Tensorflow can't use the GPU.
I have the same issue with Radeon RX570.
Does AMD looking for a solution?
Ditto. I'm running Ubuntu 18.04, ASRock x470 Taichi Ultimate motherboard, Ryzen 5 2600X and a Radeon RX580. I've installed amdgpu-pro-18.20-606296 and continue to experience 2 problems: the screen glitchiness mentioned in this thread, as well as some glitchiness with mouse cursor movements (Logitech K330/M215 wireless keyboard & mouse). I know the Logitech hardware is fine (migrated from the older system I had). I suppose the glitchy mouse could be bluetooth-related.
Any solutions out there??
I have a RX480 and I installed only the packages required to get openCL support, that actually worked in blender 2.79b
And after installing only these, no mesa drivers, no openGL drivers, the screen glitching started again
