After upgrading to proposed packages, I can also confirm that unfortunately the bug is still present. But its effects are much less than previous. I copied an image from Telegram and I was unable to paste it in Firefox (in a textbox where I could paste to it usually). However, I could paste it in Telegram itself and also LibreOffice. This also applies to texts. Also copying from Firefox and pasting into anywhere (including Firefox itself) didn't work. Even copying multiple times doesn't make any effect.
P.S.: This problem doesn't happen always, but usually. P.S. 2: It seems to me to be a problem with Firefox or whatever it uses. firefox 75.0+build3-0ubuntu1 libreoffice-writer 1:6.4.2-0ubuntu3 gir1.2-mutter-6 3.36.2-1ubuntu1~20.04.1 mutter-common 3.36.2-1ubuntu1~20.04.1 mutter 3.36.2-1ubuntu1~20.04.1 libmutter-6-0 3.36.2-1ubuntu1~20.04.1 Running Ubuntu 20.04 Focal (Linux 5.4.0-26-generic #30-Ubuntu SMP Mon Apr 20 16:58:30 UTC 2020) on a x86_64 hardware. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1852183 Title: [X11] copy/paste (clipboard) is broken in Ubuntu 19.10 & 20.04 (see comment 93) To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1852183/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
