Rendering Issues

Linux users (Windows users too?) sometimes experience rendering issues in the mind map view and/or font rendering. The first thing is to check whether you are using openjdk-7, openjdk6 should no longer be used. That means you have to install openjdk-7-jdk (or similar) package and activate it (Debian/Ubuntu: update-java-alternatives). If that doesn't help, below are some hints that have helped a bunch of people.

The Arch Linux wiki has some important hints regarding java (swing) rendering.

Relevant discussions

• artifacts when scrolling horizontally (but the workaround -Dsun.java2d.xrender=True sometimes causes other, more severe, font rendering issues)
• another posting
• another posting

Things to try

• from the Arch Linux wiki (see above)
  • run with -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true
  • install "ttf-ms-fonts" package
• -Dsun.java2d.xrender=True (see thread above)
• change the L&F to metal: Tools->Preferences->Appearance->Look and Feel
• change Tools->Preferences->Appearance->Antialias
