Github image uploads seem to be broken right now, so here's an imgur link.

Mode 7 graphics aren't working on my Fx Pak Pro. Many scan lines of the mode 7 graphics are randomly not drawn each frame, allowing the background to be seen instead. So far I've seen the problem affect Mario Kart, Runsaber, even The Flintstones: The Treasure of Sierra Madrock.

I've tried disabling many settings but nothing seems to change this.

I also noticed that in Faceball 2000 the maze walls often don't render.

I'm using the latest firmware (1.11.0) and I've tried disabling settings like in game hooks, but nothing seems to affect this.
