            Bug ID: 451549
           Summary: Launching overview with Zoom effect is not capturing
                    mouse position correctly
           Product: kwin
           Version: git-stable-Plasma/5.24
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: effects-overview

  Target Milestone: ---

SUMMARY
Suppose you are using your desktop and apply the Zoom effect (which is accessed
by default using Meta + "="). With the zoom effect enabled, launch the Overview
effect. The overview will temporarily restore the zoom to 100%, which IMO is
what should happen.

However, moving the mouse, you'll notice that the overview effect is not
capturing mouse position correctly. Therefore, if you click something, then
something else will receive the click event.

STEPS TO REPRODUCE
1. Open a few windows on your desktop (maybe 5)
2. Zoom in a bit using the Zoom effect (Meta + "=")
3. Open the overview effect (Meta + "w")
4. Notice that while you move the mouse, the window that receives focus is not
the window below the mouse pointer
5. Try to click one of the windows from the overview
6. The window that will get selected is not the window you clicked

Disabling the Zoom effect (Meta + "-") so that zoom is at 100% will restore the
correct behavior.

OBSERVED RESULT
The clicked window should be shown.

EXPECTED RESULT
Another window is shown because the mouse position is being captured
incorrectly when the Zoom effect is enabled.
