Description David Kilzer (:ddkilzer) 2007-06-15 15:43:57 PDT
* SUMMARY
When loading a particular page on usps.com, the vertical scrollbar may become detached.  Forcing a repaint fixes the issue.

* STEPS TO REPRODUCE
1. Launch Safari/WebKit.
2. Resize browser to 709x740 (full window width/height).
3. Open test page.
4. If vertical scrollbar is drawn and then drawn over, hit Reload until the issue appears.

* EXPECTED RESULTS
The vertical scrollbar should be repainted when it's removed when loading the page.

* ACTUAL RESULTS
The vertical scrollbar is not repainted when it's removed during page loading.

* REGRESSION
Can't test Safari 2.0.4 (419.3) with the 3.0 beta installed.

* NOTES
Tested with Safari 3.0 (522.11) on Mac OS X 10.4.9 (8P135) with a local debug build of WebKit r23546.

I can no longer reproduce.

This still reproduces for me with Safari 4.0.4 on 10.4.11 using attachment 15066 [details].  I think it may be timing dependent, e.g., may depend on a slower connection or loading the page on a slower Mac.  You may also have to reload the page a couple times to get it to reproduce.
