Public bug reported: In xfce4-panel sometimes the tasklist aka "Window Buttons" isn't updated correctly, causing some windows to be missing from it and also visual "gaps". The XFCE bugreport is https://gitlab.xfce.org/xfce/xfce4-panel/-/issues/188 This bug was fixed a month ago with this merge request: https://gitlab.xfce.org/xfce/xfce4-panel/-/merge_requests/66
4.14.3 from Ubuntu 20.04 is definitely affected, but as XFCE only merged the patch a month ago newer xfce4-panel versions from newer Ubuntu releases are probably affected as well. I didn't test those though. ** Affects: xfce4-panel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1968942 Title: Sometimes windows are missing in panels tasklist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-panel/+bug/1968942/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
