Hi,

I also tried it with 6900XT. I got the same results on my side.

Could you try my suggestions from the previous email and report the result?

Also, I recommend to open an issue at:

https://gitlab.freedesktop.org/drm/amd

and add all the tests results in the issue description.

Thanks
Siqueira
