If you're running on Wayland it might be related to this: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1510
It looks like a busy gnome-shell (or -extension) can eat mouse movement events, so it might eat keystrokes as well. Second way to reproduce the issue (for testing whether you experience the same issue) is in https://gitlab.gnome.org/GNOME/gnome-shell/issues/1510#note_577952 All this doesn't happen on X11, though. ** Bug watch added: gitlab.gnome.org/GNOME/gnome-shell/issues #1510 https://gitlab.gnome.org/GNOME/gnome-shell/issues/1510 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838919 Title: Slow and lost keyboard and mouse events To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1838919/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
