I've had the same problem on Windows but using DrawPoint() didn't fix it. 
In my case, the problem seemed to be caused by the use of very large 
bitmaps.  I have been using an enhanced waterfallsink that I am now 
polishing and plan to make generally available.  If you have further 
problems (or need a faster waterfallsink), let me know and I will send you a 
copy.
