The issue here is not buffer stuffing, because that only affects the 
*-location buffers - it does not impact attention.  What you are encountering 
is the "blink response" of the vision module.  It's described in the ACT-R 5 
tutorial in unit 2 (section 2.3).  Basically, if the vision module is 
attending to a location when the screen changes there will be an automatic 
reencoding of whatever is at that location.  If you clear the visual buffer 
(essentially attend to nothing) it won't happen, but if your screen can change 
rapidly that may not help and there are other measures that can be taken to 
avoid it if you can't work around it.
