I'll write a test for this when my tree is in a better state.

http://hg.mozilla.org/integration/mozilla-inbound/rev/e01a18d61dd6 Once this lands on central, I would like to get it into ff5/beta if possible.

Backed out on m-i due to test_canvas.html failures: http://hg.mozilla.org/integration/mozilla-inbound/rev/3d1b0a500fbf

We need to make sure the input pattern is set correctly when we draw the shadow.

Comment on attachment 538795 [details] [diff] [review] fix test failure Probably too late for beta, but might as well draw the attention of release drivers. This is a canvas regression in an edge case, but the fix is very simple.

Bug 668742 is about that this issue is still present in the current Firefox 5 release. Can we expect any improvement in a Firefox 5 update or do we need to wait until Firefox 6 is released? Then I know what to tell to people on he support forum that have this problem in Firefox 5. You can see a list of support threads that show this problem in Firefox 5, so we can expect to see a lot more reports about this issue. (cross posting this in bug Bug 668742 as this bug is resolved)

Thanks for confirming that. I was already expecting that (porting code to another branch is not easy), but a confirmation helps to avoid confusion and disappointment.

It's not just porting; there are just no plans to do any Firefox 5 updates before Firefox 6 ships unless a critical issue comes up; if one does an update would contain a fix for just that issue. Once Firefox 6 ships, it becomes the security update to Firefox 5, with automatic updates from 5 to 6.
