719417 - transformed subpaths don't quite work correctly with azure

Status: NEW

(Core :: Graphics: Canvas2D, defect)

Description

[Julian Viereck]

Attachment: Dump benchmark canvas test

Attached you find a very dump "benchmark" I wrote some time ago. Testing this with latest nightly that has Azure support enabled on OSX, the rendering is not correct anymore. The rotation doesn't seem to happen.

Setting gfx.canvas.azure.enabled=false in about:config fixes the broken rendering

Rendering of the TraceMonkey paper is broken in PDF.JS:

Setting gfx.canvas.azure.enabled=false in about:config fixes the broken rendering

This appears broken on Windows as well.

The pdf.js problem appears specific to Coregraphics backend and I've filed it as a separate issue (bug 720721)

It looks like this is fixed in Firefox 13. Saurabh will create a reftest from the testcase.

For reference, here's the documentation for creating a reftest: https://developer.mozilla.org/en-US/docs/Creating_reftest-based_unit_tests

The test should go in:
