This is probably an elementary thing, and me setting the rendering context all wrong. But I can't figure out what I'm doing wrong.

When I use jit.world I get this strange noise in the back of my jit.gl.videoplane. so when I move the videoplane around it does not erase the video, it behaves like a trace effect. I have made a test patch that explains it better. Also see attached image.

it's due to the erase_color 0 0 0 0, which effectively leaves garbage in the buffer when nothing is drawn at that location.

try simply initializing the context with erase_color 0 0 0 1, banging out a frame, and then setting erase_color 0 0 0 0
