I'm writing an application in WPF which basically displays a video feed from a camera, Win7 with .Net 4.5. I've tested the application with the preinstalled drivers on my HD 4000 and everything works fine. Now I've updated the driver to 15.31.3.64.3071 and all I get is a black image where the video feed should be.
Forcing my C# application to not use hardware acceleration will render everything correctly, so it really must be a driver issue.
Is there a place where I can submit the issue I've encountered?
Where can I download previous driver versions?
