In my experience this is caused by the difference in aspect ratio between the tab and the tv. Try to un-maximize Chrome, then change the height to width ratio by resizing the browser window and see if gets better.
i think it will be fixed or at least improved soon
Yep. Happens to me all the time. disappointing.
It can't be fixed. It's just how the mibox is.
All the time it happens to me as well. No idea. Just tab casting is the problem.
