332454 - drawImage() displaying garbage for transparent png

Status: RESOLVED DUPLICATE of bug 320510

(Core :: Graphics: Canvas2D, defect)

Description

[Chris Thomas (CTho) [formerly [e-mail] [e-mail]]]

Tested with SeaMonkey 1.0 on WinXP (trunk just crashes - bug 332453 - so I don't know if the bug exists there as well)

I'm using drawImage() to show a transparent png on a canvas and it's giving me garbage on the canvas.  Testcase in a bit.

It looks like a dup of bug 320510 as it's clearly a dup of bug 330478 which has been marked as dup of bug 320510 by the reporter.

This works for me with a current SeaMonkey cairo build. Can you retest with a current Cairo build if you still see this bug (for example with a Firefox trunk build)?

I filed on 1.8.0 branch, not trunk.  Resolving as dup based on comment #3.
