Lost Devices in DirextX9

[idata]

Hi,

I probably found a bug in a intel graphics driver.

DirectX 9 documentation states: 'All methods that derive from IUnknown are guaranteed to work after a device is lost.'

A DirectX application running on my computer with the following configuration crashes when calling ID3DXSprite::End on a lost device.

Intel Core i3 (2.93GHz)

Gigabyte H55M-D2H Mainboard

using onboard graphics

Windows XP Professional

You can easily reproduce that with running a sample from the DirectX SDK:

SimpleSample.exe -forceapi:9 -fullscreen -width:1024 -height:768

It's important to select a screen resolution which differs from the desktop resolution!

Now press Alt-Enter -> Access violation while calling ID3DXSprite::End on the device which is lost now.

Adding another graphics card (NVidia) to this computer and running the sample application on that device works fine.

Thanks for your feedback,

Roman
