Public bug reported: I ordinarily run KUbuntu 18.04 with desktop compositing enabled, using OpenGL 3.1 and this works quite well.
However on some occasions when compositing gets disabled, either because a game disables it or when I manually disable it in the configuration panel, Plasmashell's taskbar stops updating and its appearance gets replaced with an old version. I can tell because the application taskbar buttons are not correct and the hour is also not the right one. Reactivating composition restores normal behaviour. Only the display is affected : even if some application button is not displayed, I can still click on it if I remember where it is. The information displayed during this problem is always the same until I kill plasmashell and restart it. What is displayed seems to be the state when plasmashell was last (re)started, or when the computer resumed from either suspend or hibernation. ** Affects: plasma-workspace (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to plasma-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1811214 Title: plasmashell stops updating when compositing is disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plasma-workspace/+bug/1811214/+subscriptions -- kubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
