No clue why this happened, but the regular Ava/D.Va scene is just borked. I didn't do anything weird, besides I guess playing in fullscreen? Similar thing happens to the next scene, with the socks and shoes, and then it's normal until you cum inside, where it's normal for anal, but the body and background disappears on the vaginal variation, with only the socks and some shading left over on a black void for the right of the screen.
