I'm not sure I've correctly interpreted your snippet of code (not sure
what pState is.), but we've had similar problems. Make sure you
allocate the base for the display lists out of shared memory as well
as the the XFontStruct pointer (fontInfo?). In multi-pipe mode, we had
to allocate specific display list base's and XFontStructs for each pipe.

hope this helps,
Chris
