Mouse cursor ficks

[Przemysław Więckowski <przemyslaw wieckowski epf pl>]

 Hello,

 I update my screen 25-50 times per second ( it is needed by my 
application ) but when i do this, mouse curosr strongly flicks ( 
probably putting mouse cusor on screen is not synchronised with uptading 
whole screen by my application)

 I think that i should hide system mouse cursor and draw my own curosr 
on updated screen ( simple synchronisation ) but i'm curious if exists 
any funtion in gtk/gdk which can be used to do synchronisation withc 
system(standard gtk mouse curosr) mouse curosr.

Is there some other solution for fickering mouse cursor?
