3D viewer problem without raytracing

Layout 3D Models
1

Hello,
I just installed Kicad 6 on a new laptop.
The 3D viewer does not work properly with the default settings, via the PCB Editor and via the Footprint Editor. No board body, pads and silkscreen are completely distorted.
It works fine with Raytracing enabled.

For example, if I display a resistor R_0603_1608Metric from the provided library.
Without Raytracing, default settings :

R_0603_no_raytracing
R_0603_no_raytracing898×599 6.94 KB

With Raytracing, same angle:

R_0603_raytracing
R_0603_raytracing898×599 96.8 KB

The laptop is a Lenovo Thinkpad P14s, AMD Ryzen 7 Pro 4750U. The drivers are the last ones proposed by Lenovo, windows 10.

I’m stuck, I have no idea how to fix it.

Thank you! I had to disable the shader cache to make it work.

What is raytracing? Where is this setting in KiCAD?
