I removed all the AMD driver stuff and went back to the default 18.04 kernel and the original X.Org drivers and that seems to have solved the problem.
Still strange that the AMD drivers would be that buggy, although maybe mixing all kinds of libraries, kernels, etc. may have worsened the problem, looking back. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1885246 Title: Desktop freezes when moving window fast to other desktop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1885246/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
