Package: kde-plasma-desktop Version: 5:102 Severity: important Dear Maintainer,
Taskbar does not update its display randomly. When you open a new window, items displaying on taskbar should be updated, but they do not. And when you click on the buttons on taskbar, the displayed buttons do not match the windows, and you may open a wrong window. And the clock does not update as well. Not sure if other menu items are updated correctly or not. Alt-tab works as expected. The bug happens everyday, and it goes away around after one hour. Expected outcome: Taskbar items update after open or close window, and clock update every minute. I attach a screenshot, in which you can see that the taskbar does not show a background window (Left 4 dead 2), and the desk clock on the bottom-right corner stops working: https://i.loli.net/2020/09/05/L1TYR6IzPdsUDGq.jpg -- System Information: Debian Release: 10.5 APT prefers stable-updates APT policy: (900, 'stable-updates'), (900, 'stable'), (300, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.7.0-0.bpo.2-amd64 (SMP w/12 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=zh_CN.UTF-8, LC_CTYPE=zh_CN.UTF-8 (charmap=UTF-8), LANGUAGE=zh_CN:zh (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages kde-plasma-desktop depends on: ii kde-baseapps 4:17.08.3+5.102 ii plasma-desktop 4:5.14.5.1-1 ii plasma-workspace 4:5.14.5.1-1 ii udisks2 2.8.1-4 ii upower 0.99.10-1 Versions of packages kde-plasma-desktop recommends: ii kwin-x11 4:5.14.5-1 ii sddm 0.18.0-1 ii xserver-xorg 1:7.7+19 Versions of packages kde-plasma-desktop suggests: ii kdeconnect 1.3.3-2 -- no debconf information
