wierd video playing glitch

Hey all, wonder if anyone has any suggestions

when playing some videos (youtube so far) but not all videos my tablet (android 10) is doing something rather odd.
The video itself (not the surroundings in window mode) will every couple of seconds "jump" moving or resizing a little bit and the colours invert (red to blue) for a split second. It does this from the very beginning, it doesn't effect outside the video, I checked the same video on other devices its definitely the tablet, and its not all videos (less than half). None of the video settings in youtube made any difference. No knock on effects like slow down or effects on sound.

Any ideas?

 

no good, also its brand new so shouldnt be that kinda problem :/
