OpenJDK Icedtea6-1.8 ships with a new xrender backend that are better suited for running heavy GUI applications remote across the network.Now, any ideas how to improve that situation? How can I run java applications like the example above remotely _smoothly_
Try running your application using Icedtea6-1.8 and the following command line:
java -Dsun.java2d.xrender=True -jar circuit-construction-kit-dc_en.jarThe xrender backend are developed by Clemens Eisserer during the OpenJDK Challenge
You should also check out the video recordings from Fosdem 2009 for a in depth presentation of the xrender java2d pipeline. Its cool.
