STR: 1. Load http://ikilote.net/Programmation/CSS/Test/transform-style.htm 2. Wait for it to cycle completely. ACTUAL RESULTS: At the end of the first cycle, the purple rect leaves some invalidation artifacts in the upper-right and lower-right corners. EXPECTED RESULTS: no invalidation artifacts. (Note: bug 701656 is filed on other issues in this same testcase.)
