View improving_text_antialiasing_and_gui_performance_in_intellij_idea_on_openjdk_8.md

This is a list of tweaks to make IntelliJ IDEA work better with OpenJDK 8. Refer to System Properties for Java 2D Technology for the details of the options used below.

Note that the performance boost achieved via the OpenGL-based hardware acceleration pipeline is made possible by using the open-source Radeon driver (for AMD graphics cards) included in the latest stable version (10.3.3 as of now) of the Mesa 3D Graphics Library available in the official Fedora 21 stable repository. Therefore, the gained performance boost might vary based on the types of graphics cards and the versions of the drivers used in your system.

  1. Fixing Text Anti-aliasing in Fedora (Ubuntu users may skip this step.)
  2. Fixing text anti-aliasing in IntelliJ IDEA

In $IDEA_HOME/bin/idea64.vmoptions (or $IDEA_HOME/bin/idea.vmoptions on a x86 architecture), change
