Picture, or font problem in my macbook?

Hi, I have a MBP 2011 early upgrade model, and I have a little problem.
When I am on internet with a browser, Safari, or Firefox pictures, and chat windows (facebook, or Java chat) sometimes go crazy!
Pictures go to the background and back fast, and sometimes slide! Games and applications go normal, no problem, only in browsers! I dont know the problem, I reset the safari, clean the MBP with CCleaner, scan for virus, and this problem still.

Sorry for my grammar, I am a little bad in english! Thanks for every help!

Get rid of CCleaner. It works fine in Windows but does not work well or at all in OS X. That could be the source of your trouble. Uninstall it using their directions, do not drag it to the trash.
