Summary REGRESSION: r73340-r73429: Some Flash embeds appear clipped on Leopard

The linked page provides various calculators in Flash form. In earlier versions of webkit everything is fine, but in r73429+ the first one appears while some of the others going down the page no longer show. The rest is almost like they're covered with white. If I adjust the window height it hides and reveals parts of the first blue embed as if sliding white over top of it. Possibly connected to the available visible area of the page based on window height.

I don't see this with r73490 on Mac OS X 10.6/Intel.

Kevin: to confirm, are you on a PPC machine on Leopard? What version of Flash do you have installed?

I don't think this is compositing-related; I don't see any layers due to Flash.

I've uploaded some screenshots to better show what I'm seeing especially when resizing. http://development.rhubarbproductions.com/webkit/flash_render/ You'll see my Initial load state, scrolled down to reveal the 1st 2 calculators. Scrolling as no effect on the flash issue. Resize 1 through 4 show how the 1st calculator gets wiped upward by white as I reduced the height of my browser window. If you open all the picks in tabs with unzoomed pics, you can cycle through and follow what happens.

This looks as if clipping rectangle was now calculated incorrectly.

Any further thoughts on the potential clipping rectangle issue? Should we rename the bug something more accurate now?

Thank you for the update! Changing resolution to WORKSFORME since we don't know which exact revision between these nightlies fixed it.
