Tight bands in linear gradients have gaps, which looks ugly. This might be related to http://bugs.webkit.org/show_bug.cgi?id=16045

Looks okay on Tiger (Mac OS X 10.4.11 (8S165)) with Safari 3.0.4 (523.12.2) with original WebKit. Also looks okay with the above software using a local debug build of WebKit r29031. This should be tested on Leopard (Mac OS X 10.5) as well.

Confirmed with Safari 3.0.4 (523.15) with original WebKit on Windows XP SP2.

Confirmed with WebKit nightly r29022 with Safari 3.0.4 (5523.10.6) on Mac OS X Server 10.5.1 (9B18). Changing Hardware/OS to All. Also marking a regression since this behavior is not present on Tiger.

The fix for this issue was needed outside the WebKit project, therefore this is being resolved as 'Moved'. This should now be fixed in shipping software.
