Your video is very convincing :-) For the sake of not giving up I again stated the xubuntu iso, opened the mousepad editor just like you and typed about two pages of silly charcters.
It never got stuck the way I see it in your video. Unfortunately (sorry) all I can say is: a) you could try newer versons soon (qemu/libvirt will be bumped in a week or two I hope) in 20.04 b) I tried the qemu 4.0 you used but on a Bionic system, did you by any chance have a try on that if it might be related to the Host Desktop Environment? c) you might report that to upstream just in case anyone in the wider community might have seen that behavior before -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859545 Title: Sticky keys repeat indefinitely unless if pressed again To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1859545/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
