GLException: GLBufferObjectTracker.mapBuffer(): GL_INVALID_VALUE Invalid values: offset 0, length 0, buffer storage of target 0x8892 -> 10: GLBufferStorage[name 10, size 0, mutable usage 0x88E8, mapped null]

Actually that happens with other examples that use size(640, 360, P2D) rather than size(640, 360): GroupPShape, PathPShape, PolygonPShape. Whereas ParticleSystemPShape does not have an issue. I think the problem is createShape.

Thanks for the report… tagging @codeanticode, looks like we have a nasty regression or two in the OpenGL updates in beta 3.
