After upgrading Oneiric, some of the images and buttons in Java Applets are corrupted. I have the same version of Ubuntu and Java on my desktop with no issues, so I'm guessing it's an updated graphics driver causing the problem. I installed Java 6 JRE from Oracle because OpenJDK wasn't working. However, I have did this on both of my machines, and only my laptop has the problem. I tried re-installing the whole OS again, and then re-installing Java right after, but that didn't fix it. Interestingly, System Info reports the graphics as unknown, but lspic detects it correctly. I've attached a screen shot of the applet.

Update: I reinstalled Ubuntu, and switched to 32 bit. The problem is gone now. I figured it out by running both 32 bit and 64 bit off a flash drive, and only the 64 bit version had the problem. However, it's not a 64 bit Java issue, as my other machine is 64 bit and has no problems. So it's probably the 64 bit graphics driver. In general, I've found the intel graphics to work much better with Unity than others, so this is a surprise. The problem may have been present in 11.04 as well, since my previous install was 32 bit.
