This sounds very much like what I have been seeing recently.  It's 
almost as if clicks are being fed into a buffer in groups and counted 
out in groups of a different size; there seems to be something cyclical 
about it.  I think it started around the time that I installed kde 
4.10.5 on f17 immediately before f17 went EOL, in response to a plea for 
karma from Rex.  Since then I've FedUp-ed to f18 and mouse control is 
still workable but irritatingly unpredictable.  Gateway USB optical 
mouse, ~2006.
