When using the YouTube App on my Samsung QLED Q60a Smart TV. I have noticed that it occasionally becomes blurry when watching streams and effects the visibility of text in the chat. The resolution doesn't appear to be changing when I go into the menu when this occurs. Also when switching from one video to another sometimes a previous frame from something I just watched is displayed before the video loads. Certain videos sometimes load in slow motion and eventually return to their normal speed. I have a Amazon Firestick and it doesn't suffer from these problems. Are these bugs with the YouTube app on Samsung QLED TV's or is this more likely an issue with my TV itself?
