Hello,
This 100% issue is a known problem with XWin on 2003 and Vista; it gets
continually posted on this list.
And no, -engine 1 is not the cure, i think the problem has to be analysed
and remedied by the cygwin/cygwin-xfree developers.
Xming (same code base?!) btw does not suffer from this problem (at least not
on 2003R2; haven`t tried with Vista).
Cheers
Franz

I had similar problems and found that starting the X Server with
-engine 1 will help. Give it a try.
I tested, unfortunately, it doesn't work. And I just discovered that
opening and closing the "About" window from the tray icon causes the
same problem.
A concern is that I performed the tests using Remote Desktop. And I
just found another cygwin-xfree thread named "XWin 100% CPU usage
(Remote Desktop)" (it was on Windows 2003 Server). So Remote Desktop
might also be a factor.
Next week I will try again using a local session, but I already had
some "100% CPU" issues last week, without using Remote Desktop, so
most likely Remote Desktop is not the problem.
