A bluescreen is an error inside the windows kernel. Either the base system it
self or some drivers (i suspect the second). Software can only trigger this.
But there have been only minor changes in Cygwin/X and I doubt they could
lead to a bluescreen since no hardware access has changed.

I believe the difference with your system is some driver which was updated
before and which is not current yet.

You could build XWin with debugging output. This prints received windows
messages, some work in windows specific functions is traced but not the
network layer.

The low level unix calls (for network code) can be trace with strace.

But this will not produce useful output if the kernel goes wild and prints the
bluescreen right after the data was written to the screen. Maybe writing the
data to harddisk may help but I think the bluescreen will leave disk buffers
unwritten and you'll get a logfile which truncated a long time before the
actual crash happens.
