When toggling between fullscreen or windowed mode, buttons from overlay windows start performing the configured actions an extra time. Say if you toggle with ALT-ENTER one time, buttons start to respond two times, if you toggle again, they perform their action three times and so on. This *only* happens when you do so with the mouse. Keyboard or remote input doesn't seem to be affected.

Noticed this with the topbar home overlay.

h4. Steps to Reproduce
- start MP in either fullscreen or windowed mode (BlueTwo)
- press ALT-ENTER
- press the power button in the topbar (the cross) with the mouse (context menu appears)
- cancel the context menu by pressing the cross button
- notice the context menu appears again


h4. Additional Information
The same goes for all other buttons on overlays, like for example the previous/next buttons on the topbar.
