Description Chris Marrin 2008-11-05 14:41:18 PST 
Using WebKit nightlies r38068. Open the attached testcase and hover over the outlined box. The boxes rotate, but leave behind cruft and are rendered incorrectly when they get to their rotated state.

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.
Comment 3 Simon Fraser (smfr) 2008-11-25 16:06:17 PST 
The first testcase mostly works, but there are still some jaggies left around.

The second testcase is a separate issue; please file another bug.
