The problem is in the Xmu file StrToCurs.c in caching the cursors.
It doesn't keep a separate cache table for each display.
The following patch will make it work until R4 comes out.
The patch was kindly provided by Ralph Swick of Project Athena.

Comment out the following line in the file lib/Xmu/StrToCurs.c

 	    /* if (!cache->cursor) */
