Provide a proper kodi.log (debug-enabled) next time you do your 'bug report' , since the term "slight errors" is not a helpful description.
I'll be happy to add a log next time.
I had described at the beginning that the image freezes in some 4k films during the course of the film.
But this only happens with a few exceptions and always with the same scenes.
As I said, I will make a log for it.
