Hi Bryce, After long testing I have no problems with any key shortcuts (Ctrl+d and Ctrl+z for example), I only see this issue when using Clipboard.
I tested: Kubuntu host with Console (Qt terminal) and Ubuntu guest with GNOME terminal (GTK) - problem Kubuntu host with Console (Qt terminal) and Kubuntu guest with Console (Qt terminal) - problem Kubuntu host with Kate (Qt text editor) and Ubuntu guest with GNOME text editor (GTK) - problem Kubuntu host with Kate (Qt text editor) and Kubuntu guest with Kate (Qt text editor) - problem All after a fresh reboot - no other applications running, no extensions in GNOME. ALL shortcuts work (Ctrl+d, Ctrl+z..., Shift+Ctrl+z...), the only problem is Clipboard shortcuts and pasting / copying using mouse. That tells me that the problem is clipboard, not the input (mouse / keyboard). Please let me know if you need more info ;-). Thank you! (btw. I almost lost this post since I Ctrl+x it from Kate and then I wasn't able to Paste it using Ctrl+v or by mouse, good thing is that I didn't close the Kate so I just Ctrl+z and I copied it again ;-)) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872527 Title: Clipboard doesn't work 100% of the time in Ubuntu 20.04 (in KVM guests) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1872527/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
