Title: Delay Displaying And Erasing Notes In Graphics Display
After hitting the first note, it may take as much as a half-second for it to appear in the graphics display. In a similar fashion, when a note is held out for about two seconds, there a delay before it is erased from the graphics display. Also, latency is especially apparent in displaying chord notes (in the Chords pane).
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 be ignored.
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.
