Yes, though I don't know which one yet. However, I know Firefox is  
sending the stream and Flash consumes it. It could be either Flash is  
not writing back to the offscreen buffer (NPP_SetWindow() and  
NPP_HandleEvent()[GraphicsExpose] sequences happen though), or Firefox  
is not merging back that offscreen buffer (NPN_InvalidateRect()  
happens too).

Some things to examine:
- The contents of the pixmap XID
- Or whether Flash is actually writing to the pixmap (e.g.  
intercepting XShmPutImage()?)

Gwenole.
