Bug Description
1. Use u skin with big waveform (for more visible effect)
2. Load tracks in both decks and jump mid track (don't play)
3. Watch CPU usage (25% for me)
4. Crank up Gain knob for both decks
5. Watch CPU usage spike. (+100% for me)
6. Reset Gain knobs (Right-click)
7. Watch CPU usage goes back to normal
MacOS 10.6.7
Tested with latest http://
I compared 2 runs (Default Gain/Full gain) and attached the diff. Hopefully it is useful for a dev.

do waveforms being on or off make a difference? My first suspicion is
OpenGL.
