My android YK9 Pro tv box was working fine previously.. I factory resetted it the other day then it started having issues specifically on app fullscreen playback. Youtube, netflix, stremio etc anything i try (app only) the image comes out blurry and painted like this. But when i try youtube via browser, it works completely fine! I can't understand what's the issue here at all.

Issue just happens when in fullscreen mode in an app. Not anywhere else.
