Probably.  Programs tend to assume that any server they speak to is
either 8-bit PseudoColor or 1-bit StaticGray (ie, a "traditional color"
or a "traditional monochrome") server.

The NeXT is 2-bit StaticGray, which confuses some programs.  I have
seen code that assumes that anything deeper than 1 bit is color.  It
seems something like this afflicts netrek as well.  We had this problem
locally with xtank.

Fix the program.  Not much else to be done, unless perhaps you want to
insert a protocol filter to make the NeXT appear to be a 1-bit server.

You could, I suppose, run the MIT X-in-a-NextStep-window R3-based
server, which is a 1-bit StaticGray server.
