Disable the use of Java Direct3D?:
1. Open Control Panel –> Java –> Java Tab–> Java Applet Runtime Settings–> View Button.
2. Here in version 1.6_013 line and "Java Runtime Parameters" column enter following value: -Dsun.java2d.d3d=false (Disable use of Direct3D by Java)
Click ok and after restarting the browser see if it works fine.
If it doesn't then try replacing the runtime parameter with:
1. -Dsun.java2d.ddoffscreen=false (Disable use of DirectDraw and Direct3D by Java for off screen images, such as the Swing back buffer)
2. -Dsun.java2d.noddraw=true (Completely disable use of DirectDraw and Direct3D by Java. This avoids any problems associated with use of these APIs and their respective drivers)
