Expected Behavior

1. When moving OBS Studio's window between two screens, it does not show visual glitches, like ghost windows.
2. When unmaximing OBS Studio's window on one screen, it does not cause a ghost window on the 2nd screen for a split second.

Current Behavior

Steps to Reproduce

Moving window between two screens

1. Two screens, 2k@100% + 4k@200% (primary)
2. Open OBS Studio
3. Drag its window from one screen to another

or

Un-maximizing the OBS window

1. Two screens
2. Open OBS Studio
3. Maximize its window
4. Un-maximize the window by dragging its titlebar

Anything else we should know?

While the visual issue with un-maximizing window is always reproducible for me, the issue caused when moving the window is most reliably (if at all) reproducible, when I use a 100% and 200% scaling respectively, as described both.

Start by reproducing the issue on openSUSE KDE Plasma Wayland with two screens using 100% and 200% scaling, following the window-moving and unmaximizing steps. Trace OBS Studio's desktop window handling during monitor transitions; done means neither action produces ghost windows or other visual glitches.
