              Description

              Text editing and scrolling in Java Swing applications is slow when running on Mac OS X with a Retina display. To reproduce create a JFrame with a JTextPane and past some large text into the pane. Then start editing the text to force scrolling in the text pane. It will be slow and CPU usage for that process will go over 100%.
              The same application running on external display connected to the same machine is much faster with CPU usage never going over 50%.
              It is reproducible with JDK 8 build 117 as well. Adjusting resolution scaling in OS X System Preferences makes no difference. The problem is even more severe on MacBook Air computer - probably because their CPUs are less powerful.
