mouse or touch event flood

[Gyorgy Kovesdi <kgy teledigit eu>]

Hi,

I sent mail some days ago because my screen sometimes blinks (or remains dark) on my embedded device 
(Beagleboard + Angstrom Linux) when the screen is touched.
I found the reason: the touchscreen driver emits events too frequently, so it floods the system by touch 
events which cannot be processed fast enough.
I modified the driver to limit the event frequency, which resolved the problem. However, sometimes (rarely 
enough) i get a screen blink yet. Sometimes
the update event is followed by a release immediately, when the release event is dropped, leaving the 
corresponding button stucked. How can i avoid
this situation?

Is the screen blink a feature or a bug? If it is a feature, how can i avoid it?
