633072 - [D2D] consistent few-px failures in SVG-as-an-image tests w/ scaled circles, on Windows with D2D

Status: RESOLVED FIXED

(Core :: SVG, defect)

Description

[Daniel Holbert [:dholbert]]

On Windows with D2D enabled, some SVG-as-an-image tests fail (i.e. don't quite render the same as an equivalent <embed> or inline SVG).

Generally it's just a few pixels of difference, along one edge of a circle, with the difference being very slight (not really noticeable visually).

These tests are currently marked "random-if(d2d)" (soon to be "fails-if(d2d)", after bug 632754 lands, since they seem to reliably fail (and a few reliably pass).

I'm filing this bug on figuring out what's going wrong here and fixing it if possible.

Try server says it the bees knees... http://tbpl.mozilla.org/?tree=Try&rev=f53d142be9b6 the Android reftest failures there are because that version of the patch didn't mark the reftests as passing.
