I recently accidentally upgraded my Cygwin/X to Version 1.5.3.
One of the applications I use, amrvis, from Berkeley lab now crashes
when I try to get a line plot when it still works with a previous
version of Cygwin/X on another machine (the about dialog just says the
dialog is from 2004/3/25, but I think it's actually newer than that...
man for 'X' says version 6.8.2.0).
Here's what I could track down that seemed relevant.

Any ideas? Is this even the right place to send questions?
