Intellij IDEA jdk bundled + MBPr 13 = bad UI performance

If you have encountered the bad UI performance issue on your MBPr 13, you may take a try on JDK 9 b38.
'[macosx] Performance problems with Retina display on Mac OS X' is listed in its change list.

1. get Intellij IDEA 14 from
2. get JDK 9 b38 from
3. execute 'ln -s /Library/Java/JavaVirtualMachines/jdk1.9.0.jdk /Applications/IntelliJ\ IDEA\' in Terminal

Of course, currently JDK 9 is not officially supported in Intellij IDEA and it is a early access release.

Now JDK 8u40 Build b17 also applied the fix of UI performance on OS X.
