Hi Michel

Thanks for the link. I have applied the patch (from Kusanagi Kouichi) 
but only managed to crash the X server when writing to a pixmap. I 
recompiled Xorg, the (Intel) drivers and the app using drawing the Xv image.

Afetr applying the patch should I expect to be able to write to pixmaps, 
or have I done something wrong (left out a recompile or something else)!

Many thanks.
