I have now disabled the HideTopBar extension, but it is going to be difficult to find out if this is the cause of the problem, because freezes happens sometimes one's per month. I don't know if I can live without it such a long time. :-)
I have reported problem upstream to HideTopBar extension developer: https://github.com/mlutfy/hidetopbar/issues/266 hope to get some feedback soon. Daniel, thank you for looking into my problem. I really appreciate it. ** Bug watch added: github.com/mlutfy/hidetopbar/issues #266 https://github.com/mlutfy/hidetopbar/issues/266 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903986 Title: Ubuntu 20.04 freezes with remmina in full-screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1903986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
