I have developed a software on C# WPF 3D which uses Viewport 3D capabilities. On Intel built-in graphics (Intel UHD 770), on Windows 11 the viewport does not render correctly, I cannot distinguish the shape.
That's how it is rendered with Hardware acceleration. I have updated the OS completely and installed latest drivers.
Same program shows fine with Software rendering (but it means that Intel UHD 770 is not used for rendering, yes right).
For example, here is the same program with same settings
on NVIDIA GTX 1050 Ti videocard. Render is nice and clear
Please, I think this is a Driver issue for Intel UHD 770 on Windows 11, related to WPF 3D.
Here is a similar theme on forum, https://community.intel.com/t5/Graphics/Crash-with-UHD-770-in-WPF-applications-using-Viewport3D/m-p/1370393#M106529 but ... I did not have crash on Intel UHD 770, there is a wrong rendering
