SUMMARY When clicking the titlebar of a window with the right mouse button, the context menu opens which allows to adjust the activities on which the window is displayed. Unfortunately there is no option to simply move the window to a different activity. (See https://imgur.com/pAEjTUF). In order to move the window, one has to select the checkbox next to the new activity which results in the contextmenu being closed. The context menu then has to be opened again and the checkbox next to the current activity deselected (as we want to MOVE the window and not display it on both activities). In contrast, when right-clicking the task icon in the task manager bar, there is an option to simply move the window to one of the other activitites (see https://imgur.com/FD2G9wO). The same option should be present when opening the window title context menu. STEPS TO REPRODUCE 1. right click window title bar 2. hover over "Show in Activitites" OBSERVED RESULT Option "Move to [anotherActivity]" is NOT visible EXPECTED RESULT Option "Move to [anotherActivity]" should be visible SOFTWARE/OS VERSIONS Operating System: Kubuntu 21.10 KDE Plasma Version: 5.24.1 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.2 Kernel Version: 5.13.0-28-generic (64-bit) Graphics Platform: X11 Processors: 16 × 11th Gen Intel® Core™ i9-11950H @ 2.60GHz Memory: 31,0 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics
Apparently this feature (in the task bar) was recently added: https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/231 The author briefly discussed also adding it to the kwin context menu but that didn't happen yet as it seems. Still I think those menus should behave consistent with each other.
If the desired window is using the system provided title bar, the menu to move to another activity is showing up correctly. Tested the issue, but no error was found. The system utilizes for testing was: OS: Manjaro Linux x86_64 Kernel: 6.1.41-1-MANJARO Shell: zsh 5.9 Resolution: 2560x1440, 1920x1080 DE: Plasma 5.27.6 WM: KWin WM Theme: Oxygen Theme: [Plasma], Adwaita-dark [GTK2/3] CPU: Intel i7 4790H GPU: AMD ATI Radeon 6600 Memory: 32043MiB
