683681 - -moz-linear-gradient background image repeats if page height exceeds browser gradient with HWA off

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Michael Likouris]

Attachment: moz-linear-gradient-height.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.112 Safari/534.30

Steps to reproduce:

I've created a page, which expands as content populates it. The page reached a maximum height of 44725px. This is when I noticed a break in the background gradient.
body
	{background:-moz-linear-gradient(center top , #2092B7, #00997A) no-repeat scroll 0 0 transparent;
	height:44725px;
	}


Actual results:

The linear-gradient reaches max height and at that point the gradient begins to repeat. I was only able to reproduce this on Windows 7 Firefox 5 and 6. It doesn't seem to be an issue on the Mac (FF 5).


Expected results:

I expected the gradient to continue the height of the page as it does on the Mac.

On 64-bit Linux I see problems; I'm guessing at the 32768px boundary.

I loaded the html attached to this bug in the latest nightly and the gradient didn't repeat at all.

Michael, can you please try to reproduce this issue in safe mode and/or with a new profile?
