Mouse position aligned to screen

[paewie]

I was updating MonoGame DesktopGL to the newest Development snapshot when experiencing the following:
My Mouse.GetState() call returned the mouse's position relative to the Top-Left corner of the screen, not the GameWindow as before and expected.
Tracking this further I ended up with OpenTK.Input.Mouse.GetCursorState() returning this misaligned position which is simply copied to the MonoGame-struct's variables. Therefore I'm assuming this is a bug or whatever within this certain function. I was able to reproduce this exact behavior on two completely different Windows 10 x64 machines, no idea whether it appears on other systems, too.
Let me know if I can help or if it's my problem,
regards
