Problem description: I have rendering issues with WPF 3D content on my Intel Iris XE graphics card. With the nvidia card there is no problem. A detailed description of the problem can be found here: https://community.intel.com/t5/Graphics/Graphics-failure-with-WPF-3D-content-and-Iris-XE/m-p/1415196#M109812 As Intel can not reproduce this issue maybe someone here knows how to solve this.

Actual behavior: WPF 3D content is not rendered on Intel Iris XE graphics card. Disabling HW Acceleration at the registry solves the problem.

Expected behavior: Rendering like on the nvidia card.

Minimal repro: Use any of WPF 3D content. All apps I tried had the same problem. But to reproduce this with an open source project I tried this which had this problem also. https://github.com/helix-toolkit/helix-toolkit/tree/develop/Source/Examples/WPF/SimpleDemo

I have the same problem using WPF 3D controls in newest HP Notebook with Intel Core i5 1235U (12. Generation) processor and Intel Iris Xe graphics https://www.hp.com/de-de/shop/product.aspx?id=6F242EA&opt=ABD&sel=NTB .

We use WPF (.NET Framework) 3D Chart controls from well-known companies like Infragistics and Telerik. The 3D charts work in many tested computers, even with old Intel integrated graphics like Intel HD Graphics 4000 or Intel UHD Graphics 620.

But in newest notebook with Intel Iris Xe Graphics the 3D controls don’t work. They show few thin colored stripes on the empty 3D chart control for both Infragistics and Telerik controls (attachment). Even the standard Telerik Demo app for WPF doesn’t work.

I have made the clean install of latest beta Intel drivers 31.0.101.3616 (02-09-2022) bit this doesn’t help.

Resolved with Intel’s latest drivers. Link to a known driver that resolves this issue:
