Hmmmm... Which is your primary monitor? Monitor 1 or 2?

Monitor 1 is primary. I do not use Monitor 2 at all in extended desktop mode - it's offscreen in the top left corner for HDMI audio output only. When I do use Monitor 2 (for HDR), I use it exclusively as the only display, hence I've set the display modes on it.

A related problem is when I maximize an application window on Monitor 1 and it touches the top left corner, the animation stutters, probably due to it copying the framebuffer to Monitor 2. This should only happen when moving the window into Monitor 2's space, but it happens even on maximize.

However for this bug report, MPC-BE is not maximized and runs in a small window on Monitor 1. Minimizing it does not cause it to touch anything close to the top left corner where Monitor 2 is.

Hmmmm... If you use monitor 2 only for HDMI audio output, why do you have "switch to matching display mode" activated?

My best guess is that in minimized state, for some reason madVR considers the media player to be on monitor 2. Not sure why, though...

I use Monitor 2 exclusively sometimes for HDR and I need the display modes to correctly use it's built-in frame interpolation.

Even if it switches the display mode on Monitor 2 due to a bug, it shouldn't crash or freeze on restoring the window.
