I've had that happen to me when using MPC-HC as the player. The player didn't seem to be closing the MPC-HC process correctly when stopping playback and the GPU seemed to get tripped up.

I corrected this by using an AutoHotKey script that killed MPC-HC when I pushed stop on a Harmony remote.

You could also try using the built-in refresh rate switcher in the media player as opposed to using madVR to change refresh rates.

Here is the AutoHotKey script that I use:

There are instructions here on how to install AutoHotKey:

If you want to change the keypress, you need to Google the AutoHotKey manual for a suitable command.

This is the code snippet that kills the media player when the Media_Stop command is pressed:

$Media_Stop::
SendInput {Media_Stop}
Process, Exist, mpc-hc.exe
If (!ErrorLevel= 0)
{
Process, Close, mpc-hc.exe
}
Return
