The gist is that this is probably an incompatibility between Java's attempts at using hardware graphics acceleration and your video card driver.
The first thing to try is to update your video card driver.
If there is no update or this doesn't help, then you're stuck with disabling some or all of Java's use of hardware graphics acceleration within the Java Plug-In Control Panel. This is done by adding one or more -Dxxx=yyy style runtime parameters. As for exactly which parameters to try adding, see http://docs.oracle.com/javase/7/docs/webnotes/tsg/TSG-Desktop/html/java2d.html. You might want to start by trying -Dsun.java2d.noddraw=true.
