Never seen that before, either. 

What did you check under "general settings" in madVR? I would only check use D3D11 for presentation and present a frame for every VSync to start with. But you could experiment with those settings if that doesn't fix it. 

Did you try toggling fullscreen exclusive mode on and off under the DSPlayer settings?

Is this an HDR video? Does it have something to do with switching into the display's HDR mode? If so, you may need to try a newer video driver after a clean install of the old one.

This problem occurs both with HDR and SDR videos and is exclusive to Kodi. Mediaportal OSD does not have this problem.

I have ”D3D11 for presentation and present a frame for every VSync” and ”delay playback start until render queue is full with delay playback start after seeking too” enabled. All other settings are disabled in general settings. CPU queue size 16 and GPU 8.

I tried enabling and disabling fullscreen exclusive mode to no effect.

I have the latest AMD radeon driver installed.
