Tv flickering after a few hours (1 Viewer)

Hi there, if I watch tv a few hours it begins to flicker and I see sometimes pixels on tv. If I stop tv and restart it it goes away. Why does that happen? Logs are not attached because login over hours does not make sense, because I do not know when that happen.

Logs are attached, after a few hours tv just flickering, to solve that I have to stop playback.
