Using openSuse Tumbleweed, I have a strange behavior since some recent update. I run an older application (in fact it's Qt assistant built and using Qt 5.9.2, which is part of a commercial product) and the main window shows the flag for "on all desktops". However I can not remove that state, e.g. klicking on the window decorations sticky flag button does nothing and also via the context menu of the window decoration and selecting "move to desktop -> some single number" does not uncheck the state. It does work correctly however with other applications, also built and running against Qt 5.9.2. Any idea what can be the reason ? Operating System: openSUSE Tumbleweed 20211111 KDE Plasma Version: 5.23.2 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 Kernel Version: 5.14.14-2-default (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i5-6300U CPU @ 2.40GHz Memory: 15,5 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 520
I found out that I had an application specific setting to force it on all desktops. Don't know why. But removing it solved the issue.
