Probably related to this [Avalonia issue](https://github.com/AvaloniaUI/Avalonia/issues/11945), Intel GPUs are not fully supported with the WGL rendering mode. Do you reproduce the same if using an NVidia GPU ?

By the way, will activiz update the wgl to other libraries like angle

This is not planned and won’t probably happen without contributions to VTK to build with OpenGLES + Angle on windows. Then some work will be needed in Activiz. Contact me if you would like to help.
