I had similar problem while working on the gtk2 version of grig (well, it was 
worse
because I was drawing more aggressively and it actually crashed :). I solved it 
by
attaching a flag to the drawable indicating whether it has been exposed or not. 
The
flag is initialised to FALSE and the "exposed" event handler will then put this 
flag
to TRUE every time it is called, although nothing will put the flag back to 
FALSE
again.

I guess there is not much use for 0 msec polling anyway, since it will simply
disable the polling. Therefore, it could be removed from the options.

Isn't this mime-stuff supposed to be universal across various desktop 
environments?
I don't really know... I stopped using GNOME for good when they begun removing 
the
so-called advanced configuration options due to some fancy usability research :(
