Win32k.sys is Broken!

[James Tabor]

Hi all!
Started WinObj.exe and got this,
KeBugCheckWithTf at ntoskrnl/ke/catch.c:217
A problem has been detected and ReactOS has been shut down to prevent damage to
your computer.
The problem seems to be caused by the following file: win32k.sys
Technical information:

It locked up and was unable to back trace. Also, I tried to repeat the error
and all I get is this,

Hi!
I set the display to 1024x768 True color 32 bit and the problem goes away!
Thanks,
James

We're talking about winobj.exe from SysInternals, right? Filesize 94208
bytes.

Hmm, I'm unable to reproduce either the crash or the endless loop. What
compile time options did you use, what video driver and what virtual machine
software?
