            Bug ID: 478792
           Summary: Fullscreen OpenGL/Vulkan apps can make clicking on the
                    taskbar icons non productive
    Classification: Plasma
           Product: plasmashell
           Version: 5.27.10
          Platform: Arch Linux
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Task Manager and Icons-Only Task Manager
          Assignee: plasma-b...@kde.org

  Target Milestone: 1.0

Using Wayland and 2 monitor setup. 

If the running apps and your fullscreen OpenGL/Vulkan app are on the same
screen, clicking their icons on the taskbar will usually return you back to the
fullscreen program that is running.

STEPS TO REPRODUCE
1. Open one or several OpenGL/Vulkan program(s) in full screen (e.g.
Stellarium, Steam game with Proton). 
2. Press Win key to make the taskbar and menu visible
3. Try to click on some other app (e.g. Spotify)
4. Notice it will return you back to the Stellarium/Game
5. This happens with left mouse button - the right one works and opens setting
menus.

OBSERVED RESULT
Not registering the click with the mouse left button.

However, If the app is on the 2nd monitor, clicking the icon on the taskbar
will make that app visible on the screen, but OpenGL/Vulkan will steal the
focus again, so you will be back to the game/program.

EXPECTED RESULT
Registering clicks and shifting focus to desired app.
