Re: video tearing when composite is enabled
Alanw be careful to stay on topic, the other reports have been about a specific instance of tearing occuring in the very top part of the screen consistently.
This is likely to be a specific issue, whereas generally tearing everywhere is likely to be an unrelated problem.
EDIT: disregard that, the OP has tearing everywhere. Maybe I should start a new thread about the tearing at the top of the screen problem.
