@paelzer I have an update. After correctly applying the big fix on the guest too, the bug was still occurring but much more rarely. But now, after I tried disabling Klipper (the KDE clipboard history manager) on both host and guest, the bug seems to have disappeared completely (and copy&paste still works fine, just without history).
I have yet to test what happens: if I keep Klipper disabled without any spice agent fix; and if I keep Klipper disabled but with the small fix. -- 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/qemu/+bug/1872527/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
