[Rh7] Some surface visual issue bad representation.GPU 3090 memory fail?

I got an RTX 3090 and after an extensive day working this happened.
I was using a special custom rendering mode to debug flipped normals.
After a few minutes disappear and I did not need to restart.
I presume GPU RTX 3090 mem is hot.
