Strange color offset or "ghosting"

I have a very strange effect recently. I don't know where in my change of hardware it happened really, but I don't have it on any of our mobiles or chromecat, so it shouldn't be related to the server side, rather the PMP side .
The system is Radeon Rx 460, Win10, Plex Media Player (not the store version). The colors are offseted to each others, not in all movies, but in most movies. I don't really know where to begin, but it shouldn't have to do with the server (which BTW is on the same machine, its a HTPC but also the server).
I have provided an image in one movie that can show the effect. What is this? Has anyone seen this?
Is it some codec that's gone wild or related to the Radeon card, I had Nvidia before and then I didn't have this thing, on the other hand I had then an older PMP version for windows.
Don't know wher to start seaching for the problem.
I does look like it tries to mimic stereoscopic 3d or something.
