1 year agocorrect, but now you’ve just identified two separate types of tearing, both happening at different times. put them together and the perceived frequency will be significantly worse than it was prior.
being able to zero one of those out and only worry about the other means you can hopefully optimize a better solution - as much as one can when you can’t realistically atomically update the entire display from top to bottom.
Growing up without ubiquitous cable or satellite tv, I just did the world’s biggest double take when I read “TV has always been a subscription model”.
Just saying. We had 3 channels. 3. And on Sundays, every one of them was TV church. It was the fucking worst.
