but i still have one bug. occasionally the resolution of kodi will drop to 800x600 when i exit the external player after playing HDR content. so far all other content seems fine.
without using madvr everything works perfect but obviously no HDR switching of 4k content.

Hello.

I have exactly the same problem, I can not fix it.

1) I'm using Kodi 17.6 + external player (MPC-BE x64, for all movies by "playercorefactory" configured) + LAVFilters x64 + MadVR (x64)
System: WIN10 x64 with all newly updates and video card 1080Ti.

2) Previously, on the usual SD-content, everything was always in order.
But with the advent of HDR there was a big problem that I can not solve.

3) Very often, after I stop the HDR movie in the MPC-BE player and close MPC-BE,
the KODI shell is returned, but it does not start at the normal 4K resolution (in which it defaults to me, this is the native resolution of my OLED 65E7),
but Kodi resets the resolution to the horrible "square" 800x600.

4) This does not happen every time i start HDR movies. Sometimes two or three times I can press stop in MPC-BE, it closes and then Kodi returns with normal resolution (4K).
But, sooner or later, after the next stop of the 4K-HDR-movie, I definitely see these 800x600.
Sometimes right after the first stop.

5) If i exit Kodi after that, the desktop automatically returns from 800x600 to the normal resolution, the desktop of Windows 10 again becomes 4K.
If i then start KODI again, it opens normally, at the correct resolution.

6) This only happens with HDR-content. On any other (SD, 720p, 1080p) - KODI does not have such a problem, it always returns the previous resolution, never set 800x600.

What to do? I've already broken my head, tried various settings of KODI, MPC-BE and MadVR, but nothing helps.
Here is my full log file, taken after KODI once again dropped the resolution to 800x600 after watching the HDR-movie.

I think the most important part is this one.
It can be seen that KODI, after closing the HDR-movie, lost the screen and restored it as Generic with a resolution of 800x600.

Why is this happening? Why 800x600?
Why only with HDR, then everything else always work correctly?

The main thing is how to fix it?

I will be very grateful for the help and advice.
