I purchased a Macbook AIR July 2011 model about 2 months ago and I noticed in the last few weeks that animations have a lot of screen tearing. I thought at first it was Flash animations but I notice it in HTML animations as well. It might be a browser thing since dragging around the windows quickly doesn't show any tearing. What's causing this and how can I fix it?
You can test this yourself.
Go to http://www.360flex.com/. Click on the left and right arrows on the banner. Notice the screen tearing and redraw artifacts specifically on the images.
