Issues Running Slay Sample on 5.1 on a G14 (AMD 6900HS, RX6800S)

Has anyone using an RX 6800S tries running the Slay content sample in 5.1?
I am getting weird white artifacting instantly (see image). Also the GPU reports exceding memory (GPU has 8gb).
I also have a notebook with a 3080 8gb and I am getting nothing like that!

The Memory issue is the same on the Lyra sample. But at least there is n artifacting.

Any help would be highly appreciated
