I’m running the Fedora 41 KDE spin on my Framework 16. When I right click on a window in the task manager, go to the “Show in Activities” sub menu and then click “Move to ActivityName”, it makes the window available on all activities. If I repeat those steps a second time, it then moves the window to the activity.
I wanted to check here if this was intended behavior before I went and filed a proper bug report.
I’m including a screenshot showing the menu in question as a visualization aid and the “About This System” page in the system settings app for all of the kde related version numbers.
