Access violation in igdumd32.dll

Hi,

We use MSHTML library to embed MS Internet Explorer component into our application. MS Internet Explorer component provides feature that allows us to enable/disable GPU acceleration during web page rendering. It's an internal MS IE feature. When we enable this feature on Windows 7 we receive access violation (AV) error in our app. We collected dump file with more info about this access violation error and in dump file we see the following call stack that causes AV:

0x1e992057 igdumd32!OpenAdapter+1569f8 igdumd32!OpenAdapter+1219b0 igdumd32!OpenAdapter+ca021 igdumd32!OpenAdapter+9084e igdumd32!OpenAdapter+7914e D3D10Level9!LDDMUMDevice::UnderlyingCreateDecode+107 D3D10Level9!UMDevice::CreateDecodeContext_Default+4a d3d11!CDecodeContext::CLS::FinalConstruct+81 d3d11!TCLSWrappers<CDecodeContext>::CLSFinalConstructFn+10 d3d11!CLayeredObjectWithCLS<CDecodeContext>::FinalConstruct+71 d3d11!CLayeredObjectWithCLS<CDecodeContext>::CreateInstance+bb d3d11!CDevice::CreateLayeredChild+743 d3d11!CBridgeImpl<ID3D11LayeredDevice,ID3D11LayeredDevice,CLayeredObject<CDevice> >::CreateLayeredChild+20 d3d11!NDXGI::CDevice::CreateLayeredChild+205 d3d11!CBridgeImpl<ID3D11LayeredDevice,ID3D11LayeredDevice,CLayeredObject<NDXGI::CDevice> >::CreateLayeredChild+22 d3d11!NOutermost::CDeviceChild::FinalConstruct+1e d3d11!CUseCountedObject<NOutermost::CDeviceChild>::CreateInstance+66 d3d11!NOutermost::CDevice::CreateLayeredChild+d0 d3d11!CDevice::CreateVideoDecoder+a2 msmpeg2vdec+64026 msmpeg2vdec+63445 msmpeg2vdec+740e6 msmpeg2vdec+71c0e msmpeg2vdec+e0991 msmpeg2vdec+13a17b msmpeg2vdec+d764c msmpeg2vdec+c5b95 kernel32!BaseThreadInitThunk+e ntdll!__RtlUserThreadStart+70 ntdll!_RtlUserThreadStart+1b Access violation happens in the igdumd32.dll module that is used when GPU acceleration feature is enabled. We tested our application with the latest version of igdumd32.dll (9.17.10.3517) and we still see same AV. Could you please take a look at this call stack and let me know what might cause this error. We can provide the DMP file for you, so you could analyse it better. Just let me know. Any help, workarounds or suggestions would be appreciated.

Update: with the latest version of driver this issue isn't reproducible anymore.
