I'm also affected by this bug and I think this is a pretty severe bug. I can't understand the 'medium' flag.
Two things I noticed that hopefully help to identify the problem: A) Every other copy fails for me. After starting the program, the first copy always works. The second copy fails and so on. B) it only affects specific programs. For my machine, it only effects one program for me (notepad++(wine) installed with snap). In notepad+ every other copy fails in the sense that nothing is copied. Some specifics on B): 1. I open notepad++ and write '12345' and '67890' 2. I select '12345' and copy it. It works, '12345' is pasted both into notepad++ and any other program like firefox 3. I select '67890' and try to copy. It fails, notepad++ doesn't paste anything. Firefox allows a paste, but '12345' is pasted -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879968 Title: copy/paste still sometimes fails in LibreOffice on mutter 3.36.2 To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1879968/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
