Visual glitch? (Garbage Collection)

Hi all,
I'm finding this happens with most of my sketches.
There is a sort of "dragging" effect, every few seconds, where the points appear to skip back for a frame.
I've put together this simple sketch to demonstrate what I mean.
If my code is causing it, i'd be keen to know why, but it seems to happen more when there is less going on, like it's the opposite to slowdown. Can anyone explain it? perhaps it's just my system but I don;t think so...
Thanks in advance
Dave
