The AMD Open Source driver has the same problem, may even be worse. Also sometimes when rebooting through ssh the computer is locking up, so I have to hard reset it.

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.
