Algodoo

Algodoo is a sophisticated physics simulation program (app) that must calculate position, velocity, and rotation of many objects in a scene. When motions occur rapidly (as they do in your scene) your computer cannot calculate those parameters fast enough, which sometimes causes weird motions or collisions, as what happens in your recent scene. It's not really a "glitch". It's simply due to your computer not being able to keep up with the rapid calculations that Algodoo requires.

Suggestion: Do not create scenes that have rapidly moving objects.
