Yes, I know it does. I think I have a clue as to why is does,
but it's not a huge priority as of right now. I will fix it some time in

This is because OpenGL resorts to software rendering. To fix this, download
the latest drivers for your video card, and make sure that OpenGL hardware
acceleration is supported.
There is a bug in the collision detection. The game will not register a
hit if the ball collides with the very edge of a bat, causing the ball to
go through the bat. This will be fixed soon.
