Still broken

The fix to the stutter wasn't quite as good as I had hoped. I've spent days staring at moving lines and I need to try something else. My current conclusion is that the stutter is a universal problem with windowed stuff but is only really noticeable in cases like this. Gotta take some time off lines moving across the screen so I'm going to try to make a little thing I've had in my head for a few months. It's about fish!
