White lines in upper left corner of video

[tekslave]

Some videos that I ripped and compressed have changing white lines in the upper left corner when played on my co-star media player. I have searched my ass off looking for an explanation as to what they are and how to remove/avoid them.
BluRay disk
Ripped with MakeMKV
Compressed with Handbrake

Here is a picture of the anomaly


Any help would be greatly appreciated

If the lines only show up in this scenario.....then it's the media player or the television.

then it's the media player or the television.

If that turns out to be the case try a simpler preset in Handbrake.

It only happens with some videos. I think it is some kind of embedded information. Yes the media player is not filtering something. When I play the MP4 on my computer I see no lines.

Get a better media player ?

Or if you want to try to figure out what causes it, you can look at mediainfo(view=>text) and compare what is different about the videos that have the artifacts
