Xwin stackdump while logging into RH8 with KDE as window manager

[Harold L Hunt II]

Joel,

Okay, I have a couple more easy things to try that might have an effect:

1) Use "-fullscreen" to run in a full screen window... you may be seeing 
the results of some sort of image scaling problem.  Running in full 
screen gives you a standard aspect ratio screen, so it might aleviate 
the problem.

2) Use "-engine 1".  This uses the GDI engine instead of DirectDraw. 
GDI may not be affected in the same way as DirectDraw.

3) Use "-clipupdates 10".  This will group together all updates to the 
Cygwin/XFree86 window that have more than 10 regions in them.  This may 
prevent your problem from causing a crash.

4) Don't use the "2>/dev/null" in your startx script anymore.  At best 
it is not needed since we are not a console app... at worst it is 
redirecting a file handle that is not expected and may be causing 
problems.  In fact, please try using startxdmcp.bat... it has much fewer 
side effects that any other method of starting the server and will rule 
out a few questions in my mind.

I understand what your problem is.  I also know that sometimes strange 
things happen that I do not expect and trying a few things that don't 
make sense often ends up fixing the problem and alerting me to something 
that I didn't know what happening.

Thanks for testing,

Harold
