SUMMARY Windows set to belong to all virtual desktops are raised and shown when switching virtual desktops (e.g. when using the cube animation). STEPS TO REPRODUCE 1. Open window, right-click title bar->Desktops->"all desktops" 2. Open maximized window that only appears on current or target desktop. 2. switch desktops using e.g. cube effect transition OBSERVED RESULT The "all desktops" window is raised above the window that rotates in or out with the virtual desktop change. After the transition is complete, the "all desktops" window is hidden behind the active window for the new virtual desktop. It effectively pops to the front during the virtual desktop transition, and disappears again afterwards. EXPECTED RESULT Either the all desktops windows are rendered on all cube faces or they're just not shown at all. Right now they pop op in your face, surprising you, and also hiding parts of the transition animation. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (available in About System) KDE Plasma Version: 5.22.0 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2+kde+r23 ADDITIONAL INFORMATION SHowing the desktops on a cube (using the desktop cube effect with the standard ctrl-F11 shortcut) shows "all desktops" windows rendered on each cube face. This would be my expected behaviour for the transition effect as well.
This is intentional. Some people find it very confusing that windows that are on all desktops are animated.
Indeed.
