Here's another test case which is similar to the reported bug: http://homepage.mac.com/ebailey/webkit/exp7/index.html Artifacts can be seen in the reflection after a 10 degree rotation. These artifacts appear in all cases except when not rotated.

The first testcase mostly works, but there are still some jaggies left around. The second testcase is a separate issue; please file another bug.
