A +relay trace shows error occurs in CreateDIBSection:

Gives normal (?) values:

RGB

The above does look a _little_ odd.  Comparison: 
 DIB_CreateDIBSection    10, -200, 32 bpp 
 X11DRV_CreateDIBSection 10,  200, 16 bpp 
 
But I'm unsure whether to worry about it. 
 
 
I think that xorg-server-1.0.2-r3/dix/dispatch.c (attaching momentarily) is 
where the failure happens. 
Looking at the source, there are two places where BadValue can be returned. 
 
One of them sets errorValue to bit depth, which would be odd (we're seeing 
errorValue == 0). 
 
The other sets errorValue explicitly to 0, so I think it's more likely to be 
the culprit. 
 
Code looks like this: 
	if (!stuff->width || !stuff->height) 
	{ 
		client->errorValue = 0; 
		return BadValue; 
	} 
 
 
Unless width/height got corrupted on the way (I don't know how it propagates 
from x11drv to dispatch.c), this statement fails: 
	if (!10 || !200) 
 
 
That would be odd, wouldn't it?
