Or by chance do you see it in 'lines' where the pool seams are? This happens in my pool. I also have a pad underneath the liner that is taped together and the dirt wants to settle in those lines as well. No matter how well I vacuum and think I have the pool really clean, as soon as the water quiets down, the dirt that is in suspension settle back down and I once again can see those same lines. Not saying this is what is happening in your pool, but just offering that as another possibility.
