Hello

I have a display problem in the viewpport when I use raytracing (especially cast ray traced shadows)
My screen starts to sparkle, the thumbails and the viewport of the materials turn white) (see image bug graphic).

Note that when I put the “cast ray traced” in disabled mode on my lights the problem disappears in my main viewport but remains in the thumbails and the viewport of the materials.

Difficult to work in its conditions.

Here is my setting rendering (see image rendering setting)

My pc configuration

Laptop rog strix g 15
AMD ryzen 9 5900hx with radeon graphics
AMD radeon 6800M GDDR6 12GB (384000 Gbytes/s)
16 GB memory

All my pc is up to date for windows 10 (22H2
![rendering setting|690x462]
and I installed the latest AMD graphics driver recommended by EPic.

Thanks in advance.

In Project settings Hardware Raytracing, Uncheck Raytrace Skylight. That’s causing the issue.
