well I am trying to draw 2 streams of yuv420 frames to 2 windows

I am doing XvShmPutImage , once to first window and once to another once to
first, once to another etc.

I use separate shared memories for each window.

I am doing it very slowly (usleep(3000000) between each draw). the strange
thing is that when I draw to one of the windows the second goes BLUE! the
more interesting is that if I get one of the windows behind something such
that clipping eats it all) the second behaves normally and doesn't present
anything blue.


it seems to me that there is some problem in i810_video driver, I just can't
think of anything else!

(First guess was that I get Exposure events and doesn't respond to them, but
after checking I know that I don't get them at all (only when I raise the
window again)).

any thoughs?

Michael
