Title: Delay Displaying Notes From MIDI Player In Graphics Display

Detailed Description:

There is a delay in displaying (and erasing) notes from the MIDI player in the graphics display.

Cause Of Problem:

Some of the graphics-display latency issues in early versions of Oracle Java on Mac OS X have appeared in Open Java 8.


This is annoying, but can usually be ignored, unless you're trying to learn music by matching the notes from the player in the graphics display.

Fix Available (in Version 1.24, published August 9th 2016):

The graphics-latency fixes for Oracle Java on Mac, have been included in the Linux version (which now uses Open Java 8), and a few more fixes have been added.
