Hi, I think this is a bug. The pen trails work different in a playfield
than in the world. In the world the background morph is draw above the pen
trails, but in the playfield the pen trails are draw above the background.
I believe the latter is the correct.

I looked at the code briefly and I couldn't find the error. In fact, it's
weird because if I evaluate

World drawOn: Display getCanvas

in a workspace the pen trails are draw correctly. Any ideas?
