It seems to be only the resolution 1280x1080 which causes this distorted picture.
I have two channels with this resolution and both of them are showing the same behavior while switching between progressive channels.

So the problem is there in a December 2018 build? I'm not sure what might be causing it... maybe @fritsch has some ideas?

Yes, yesterday i tested back to december builds with same behavoir (really dont know why i never noticed this before...).
Like some other users reported in Kodinerds forum, these '1280x1080-specific-german-channels' seem to be a frequent problem.
If i can do anything else for further investigations, just let me know!
