Opening the Widget Explorer moves windows that are opened on a secondary screen away when running under Wayland.
STEPS TO REPRODUCE
0. Have multiple monitors attached
1. Start wayland session (wayland or full-wayland)
2. Put a random window (e.g. Dolphin) on the secondary screen, not maximized
3. Open Widget Explorer on secondary screen
4. Window is moved away.
Window should stay in place, Widget Explorer should overlay it.
Window position is messed with.
