My ROG 3 is 8gb/128gb variant.
I am also facing the same black crush issue. It is very irritating and annoying. Also there is a shift in red tint while changing refresh rates and lowering the brightness. Asus should fix this ASAP
Look at the screenshots, literally nothing is visible clearly.
Check my software version too.
For red tint issue check this keyboard screenshot, the layout and the space button appears in brown rather than black.
