I have a WPF application crashing on the client machine. My initial analysis shows that this is because of H/W acceleration and disabling H/W acceleration at a registry level solves the issue. Now I have to make sure that this is caused because of H/W acceleration. I have the crash dumps available which has a stack trace,

How do I ensure that crash is caused by H/W acceleration issue by looking at the above data? I am guessing VIDEOPRT!pVideoPortDispatch+0xabf indicates some error with the rendering. Is that correct?
I am using WinDebug to view the crash dump.
Do a quick internet search and you should find that,
igxpmp32.sys file information
The process Intel Graphics Miniport Driver belongs to the software Intel Graphics Accelerator Drivers for Windows NT(R) by Intel Corporation (www.intel.com).
igxpdx32 should also be from Intel. So your guess on the root cause should be correct.
So you may contact Intel support and let them analyze the dump to confirm whether this is a known issue.
It is almost impossible for an outsider to analyze such dumps, as private symbols are not available.
