I experience this problem in all kinds of editors (LibreOffice, RStudio, Evolution, Kate), and also sometimes when creating screen dumps to the clipboard (ctrl+shift+print screen). I also thought it was connected to Clipboard Indicator, but it didn't help de-activating it.
But, hopefully good news ahead: The bug should be fixed in gtk3 3.24.13 and mutter 3.34.2 according https://gitlab.gnome.org/GNOME/mutter/issues/878#note_642048. So now we just have to wait for Ubuntu to get to these versions. Anyway we could get this first in line of updates? - it is extremely annoying. ** Bug watch added: gitlab.gnome.org/GNOME/mutter/issues #878 https://gitlab.gnome.org/GNOME/mutter/issues/878 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852183 Title: [X11] copy/paste (clipboard) is broken in Ubuntu 19.10 To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1852183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
