Font rendering is different when using -multiwindow

[Matt D.]

I'm unfamiliar with X but I've been digging around the source code to 
see if I can find anything.

It seems like all of the text drawing is done by functions in dixfont.c, 
is this correct? Is there a different rasterizer between normal and 
multiwindowed mode?

I tried specifying all of the various options available through the 
-engine parameter, such as '-engine 1' but with no change.
