CRT Pi - No Scanlines

Hello All,

First, the Picade is great. I built the newest model with the 10 inch screen and have had a blast playing it.

In the past, on my Pi I have used CRT Pi as the shader for all of my console/arcade games. I know it has a scanline effect; however, when I run it on my Picade the scanline effect is asbent… has anyone had this issue as well? Any idea on the cause?

Thanks for any and all suggestions.
