Dont think we should be failing acid 2 tests.  blocking fennec 2.0?

Comment 2

Yep, confirmed on build:

Mozilla/5.0 (X11; U; Linux armv71; Nokia N900; en-US; rv:2.0b2pre) Gecko/20100802 Namoroka/4.0b3pre Fennec/2.0a1pre

Also reproducible in desktop builds, both Fennec 1.1 and 2.0a1.

Comment 4

[Matt Brubeck (:mbrubeck)]

The test fails in row 4-5, where two overlapping images must be offset by exactly one pixel to form a solid yellow area:
http://www.webstandards.org/action/acid2/guide/#row-4-5

This fails because of rounding issues when zoomed in or out.  (The test also fails when zoomed in desktop Firefox and other browsers.)  The test renders correctly some of the time when Fennec's zoom level is set to 100% (control+shift+z) or higher, but other times it still fails in the same place.

Comment 5

[Matt Brubeck (:mbrubeck)]

The default browsers in iOS 3.1 and Android 2.2 also fail the test.  The Acid2 guide says, *"Changing the zoom level, minimum font size, applying a fit-to-width algorithm, or making other changes may alter the rendition of the Acid2 page without this constituting a failure in compliance."*

I don't think this should block Fennec 2.0.

[Tony Chung [:tchung]]

Based on comment 5, Will Acid 2 ever pass on Fennec?  If not, should we disable out of litmus

Comment 8

[Matt Brubeck (:mbrubeck)]

I don't think we have any plans to make Acid 2 test on Fennec.

Comment 9

[Kevin Brosnan [Ex-Mozilla]]

Disabling the Litmus test.
