--- Comment #10 from Mirek Kratochvil (exa.exa@gmail.com) --- Hello everyone,
would the artefacts look like on this picture, or am I having a different issue? http://e-x-a.org/stuff/amdgpu-artefacts.jpg (Taken with a phone, as the artefacts are not screenshottable.)
The squares appear around small stuff that changes (esp. terminal text) and disappear in around half a second. Notably, they are only seen in xfce (suspect compositor is needed); not in LightDM (which does not do composition) nor around any frequently refreshed/accelerated surface (glxgears and animations in forefox are clean.)
Mine is:

The problem happens on all 5.2 kernels I tried (from debian). "Debian stable" 4.19 and one 5.1 I tried are OK.
If this is a different kind of artifacts, please let me know (I'd open a different kind of bug.)
Thanks in advance! -mk
