DX12 produces other visual bugs (lots of colored bright lights at the bottom of the screen when entering water or sometimes a "filmstrip" band on the bottom of the screen everywhere else).
I have not noticed problems on the few DX12 games I have tried lately.
When I do find glitches I post them on my site depending on the source of the problems
