Application Video Rendering Issues on Specific processors\graphics drivers

[CatSysEng]

We are experiencing an issue with video playback crashing our app which is a DirectX-9 video editing application. The problem occurs with pretty much any newer drivers (Intel GPU) on newer Intel hardware (Ultra 7 and some Arc enabled laptops). If we use 31.x.x.x graphics drivers, we don't see this problem, but if we upgrade to 32.x.x.x we see crashes. These crashes are generally heap corruptions in ntdll.dll. We do not see these crashes on older Intel hardware, or with the new hardware using older drivers. It is fairly easy to reproduce these crashes at will. Example stacks: Unhandled exception at 0x7708DCAF (ntdll.dll) in Thunder2.exe.26168.dmp: 0xC0000374: A heap has been corrupted (parameters: 0x770CC920). The crashes seem to occur during calls to initialize the Intel decoder (software or hardware).

Hello @CatSysEng and Welcome to our Intel Software and Game Developer Support forum!

Thank you for all the details you have shared, however we need more info and a fast way to reproduce and confirm the regression you have identified.

Question: The application you have developed has been released already or is it under development?
Have a look at the requirements we need to fulfill in order to report any issue with Intel GFX internally (pay special attention to the NDA part)

However, if there's a way you can trigger the exception with a small project with code, that would be fantastic.

Also, by saying any Intel GPU you mean both mobile and desktop?

Make sure to include the impact of this issue in your development so we can share with the driver dev team once issue has been verified and confirmed on our end.

Thanks a lot! Looking forward to hear from you

Karen
