Title: Response Slow Matching Notes In Nimbus LAF

Detailed Description:

When using the Nimbus look-and-feel while you're either recording, or matching (playing) notes displayed from the MIDI Player, response is sluggish on a slow machine.

Cause Of Problem:

The way the Nimbus look-and-feel updates the musical staff graphics display on Linux, is much less efficient than the other available look-and-feel settings.

Work-Around:

If you notice this problem, don't use the Nimbus look-and-feel (LAF). GTK+ is the native look-and-feel for Linux, and it avoids the efficiency problem. It also has a better display of slider-controls.
