For all who used the workaround #61: The current update xserver-xorg-video-amdgpu-hwe-18.04:amd64 19.0.1-1ubuntu1~18.04.1 19.1.0-1~18.04.1 overwrites the file /usr/lib/xorg/modules/drivers/amdgpu_drv.so (file date May 21 09:16) and the bug returns again.
It is one step forward one step back ...
Hence either apply the workaround #61 again or step back to my suggested workaround #54.
