I am using PowerDvD 20 and i have a strange issue. I tried running a Bluray 4k movie and if I click the "Crop to fill" - everything is fine, but if i want toy use "Keep aspect ratio" the image remains dark as if I still am moving the mouse, while the movie is playing, but I am not and cannot get rid of that??
I made a small demo of my issue - https://www.youtube.com/watch?v=RzTN72TgZQQ
