Can you reproduce it with latest Webkit Nightly?

Yes, it reproduces on the WebKit Nightly r133465.
Thanks for your feedback. Could you please file also a report at https://bugs.webkit.org/ and post the webkit-bug-no here to track the issue? Thanks in advance.
Also, please note this affects customers using Tumult Hype (http://tumult.com/hype).

This also appears to affect animating left/top and border-radius properties.
It is still a problem in the latest Chrome Canary build, but this has recently been fixed in the latest WebKit nightly:
https://bugs.webkit.org/show_bug.cgi?id=101252

This is not just background-color, but also the text color property.  I've attached a reproduction for this case.
The WebKit fix does not seem to address it.

This appears to be fixed, our behavior on the test case from comment 14 now matches FF and expectations. Please verify or reopen. Thanks!
