it looks like something went wrong with the content of your post, but as I can see your headline, I assume you have problems playing your games, because your screen turns green even though you can still hear audio.
On which device do you have this problem: On the TV, Chrome Browser or mobile phone?
Can you try the other devices as well to isolate the issue (if it only appears on one specific device)?
Is this happening to all games or only in specific games?
Is this a problem since the beginning or did this appear after you've done anything, e.g. doing an update on the device or similar?
