Load the testcase, you should not see the white parts. Works in Safari 4, broken in WebKit nightly.

I will investigate
Comment 3 Peter Kasting 2009-06-17 11:41:25 PDT 
Just for reference, is this using run-safari to run the CG port, or is this GTK+, Cairo/win, or some other WebKit port?

If this is the CG port I'm surprised this would be broken as I haven't touched anything that would affect that...

This in on Leopard, running via WebKit nightly package.
Comment 5 Dave Hyatt 2009-06-17 12:15:51 PDT 
This image renders correctly for me on Leopard with latest ToT...
Comment 6 Peter Kasting 2009-06-17 12:21:17 PDT 
From IRC: there is some code in the CG port that looks suspicious, since it reports that the image doesn't have alpha if it has no image type.  But hyatt claims the frame is cached and the type determined before anyone asks this question so that shouldn't matter.

I am reassigning to hyatt since this looks like not me, but this may just be Not Reproducible.

Well I am on MacOSX 10.5.7 and this is broken for last 24 hours or so.
Comment 8 Ismail Donmez 2009-06-17 12:41:27 PDT 
This looks correct here now , something weird is going on. Marking as invalid for now. Sorry for the noise.
Comment 9 Ismail Donmez 2009-06-17 13:16:59 PDT 
Well it fails randomly, so it explains why it succeeds some times.

This is a bug in GMail Offline implementation.
