Wrong window size after fullscreen

[ovejota]

In Windows 10, when I move the mpv.net window to my third monitor, double-click to maximize it, and then double-click again to return to windowed mode, the window size is not restored to its previous size. Instead, it shrinks for some reason. If I repeat the process, it shrinks even further, until only the top-right buttons (minimize, maximize, close) remain visible.

This only happens if i enter/leave full screen by double-clicking. Not if I click the button on the top right corner.

On that monitor, Windows display scaling is set to 200% (text, apps, etc.). Could this be related? Is there any solution?

I recorded a quick video with the issue.
