Since beginning of September the bug disappeared for me. I'm not sure what update caused it but the usual suspects are: linux-image-5.4.0-45-generic:amd64 (5.4.0-45.49~18.04.2, automatic) with its kernel module amdgpu.ko or some xorg-...-hwe parts or a combination of them.

But I tried with a boot of a kernel 5.3.0-40 and the bug emerged again. So it is more likely that it was a kernel related problem.

I have to note that I removed the line with "EnablePageFlip" within the configuration file "/usr/share/X11/xorg.conf.d/10-amdgpu.conf" of my suggested workaround #54 like this:

Section "OutputClass"
        Identifier "AMDgpu"
        MatchDriver "amdgpu"
        Driver "amdgpu"
EndSection
