Maybe you should try calling ‘x-synchronize’ first.  Without that I can
get all sorts of things like, for example,

Lisp Backtrace:
"redisplay_internal (C function)" (0x0)

But with ‘x-synchronize’ I reliably get the Xaw3dComputeTopShadowRGB
bug.

BTW could you try this with a motif build?  Here this gets me the backtrace

and the usual BadPixmap error.  So the bug behind all this is probably
neither scroll bar nor menu related after all.  I conjecture that
deleting the last GUI frame from a TTY started server messes up
something we do not initialize properly when invoking another GUI client
from it.  This conjecture is supported by the fact that when I leave a
client frame open and fire up a new terminal, I can invoke the client
from the new terminal as often as I want without any problems ...
