record one of these event sequences with evemu-record and attach it here please, thanks. the sequence should be short and illustrate the problem. I can only see the events so if you stop moving your finger I won't be able to notice the difference between that and a cursor stalling.
the side to side log contains 5 sequences where I move the mouse back and forth. when I detected a stall I [ctrl]-c. the trackpad did better than average surviving several seconds in some case, stalls being brief. the second file is me attempting to drag a window. these kinds of actions tend to be very jerky. this particular one there were what appeared to be three stalls lasting for a longer duration. I can't quite "put my finger" on a specific trigger here but the problem is more prevalent (and annoying) during these kinds of short lived actions. ie. clicking a button or moving a window... especially when you change finger during movement thus introducing a pressure change.
