Public bug reported:
For a long time sometimes my desktop freezes suddenly and it took me a
long time to find when. It turns out sometimes the desktop freezes when
I move a window fast from one desktop to another, normally I would move
it to the right.
OS is Ubuntu 18.04 and the issue occurs (as far as I remember) with the
Open Source drivers and the AMD drivers. When using some default
setting/driver the issue does not occur, but then screen updates are
very slow.
I am using an MSI H81M-P33 motherboard, processor i5-4460, AMD Radeon HD
7700 Series (according to AMD driver). Monitor is AOC 1920x1080.
I tried many things, like different kernal versions and different
drivers. The currently installed AMD drivers don't work with the 5.3
kernel. I did not recently use something like kernel 5.0, so I don't
know if the issue is solved in later kernels.
I found some similar reports, but they all or mostly seem to relate to
laptops. While writing this report my desktop crashed again and I was
not moving a window, but just resizing it from the top down.
I can access the system through ssh and just changed the drivers from
AMD pro to AMD open source. Not sure what the effect is. More details
available if needed.
I would appreciate this would be solved, as it is pretty annoying to
restart my computer several times a day and sometimes losing work.
