Summary

Hi,
If you have multiple monitors, the BG software uses wrong window size. I have one in landscape mode and the secondary is in portrait, but when I make one of the VLC window borderless (OpenGL clone window), then it does not use the correct display size, but the combined size of the two (3000x1920).

Steps to reproduce

1. Have a multi monitor setup
2. Open VLC player with multiple window (.\vlc.exe --video-splitter=clone --clone-vout-list=glwin32:glwin32
3. Select the player window process and make it borderless

I have tried with both monitor in landscape mode, the issue is still the same. From the picture it is clear that the program counts from the full canvas size and not only the display size it should show the application in full. Even if you set to make the screen borderless on \.\DISPLAY2 it takes the full combined display size (3840*1080 in this case), it resizes the window according to this size then puts the borderless window in the middle of the \.\DISPLAY2. So I think the problem's root is the base of the calculation.
