I am still playing with graphics and am curious if there's any way animations can be displayed using double buffering with plan9? What I have done is a simple rectangle that changes size and generaly bumps in the corners of the window. The effect is that on my ATI video card, the refresh is not perfect, even if I have quite a delay between the redraws -- there's still some flicker. Has there been anything done to enable displaying higher refresh rate image under plan9 (i.e. animations)? If yes, how would one accomplish that? The way I have implemented it is by simply changing the coordinates of a rectangle, redrawing the screen with default color and drawing on top of it. I'd be happy to see if anyone else has done anything requiring more than 10-24 refreshes a second... Please bare with my silly questions, having in mind that I'm still learning :) andrey
