However, when running in mergedfb mode, the right ~1/3rd of the second

of the second monitor work great.  Have you seen anything like that
before, or should I file a separate bug on that?  The best way I could
describe it is garbage, but it seems like some of the graphics are
trying to be displayed.

How wide is your mergedfb desktop?  There are some width and height
limitations in the 3D engine.

It is 3200x1200. I would say the 3D engine appears to have problems when X is between ~2667 and 3199. What are the limits? Are they in the card or in the driver?
