My old demos are working well up until FFX4 Beta 6, but latest builds are broken, compare rendering... 

Reproducible: Always

Steps to Reproduce:
1. Open file from URL or from attachment
2 [review]. Compare rendering of stroke of top front text
Actual Results:  
Stroke is too bright, almost white...

Expected Results:  
Stroke should be darker, visible...

Could you narrow down the range when things changed to a single day using please?

You would be looking for mozilla-central builds.
Yes, sure. There is result of my investigation

and result is that problem is in some patch to version 2010-11-06. Hope this will help.
That produces this range:

  Bug 484953 - speed up display of text that is both stroked and filled

Looks like a strong candidate.

I can confirm this bug (on Linux), comparing my nightly vs. Firefox 3.6

Summary: Gradients on stroke broken (probably after change of HW acceleration turned on) → Gradients on stroke broken
Perhaps that setMatrix getMatrix foo was needed after all...

Attached patch patch with reftest (obsolete) — Splinter Review
This just reverts the removal of the set/getMatrix lines from bug 484953. Included is a reftest so we don't remove these lines again.

This turned the Windows optimized reftests orange.  I backed the patch out.  Bug 614324 has been filed for the oranges.
Depends on: 614324
Resolution: FIXED → ---
The reftests look like they would if the patch never landed. I'll try a try server build but at the moment it doesn't make much sense to me what's happened.
I just built an optimized Windows build and ran it and the reftest passes. I might try landing this with the reftests random_if on windows and then enable them on windows a day or two later to ensure we've had complete rebuilds there.
relanded with windows marked as random_if.

Does not appear to have been fixed.

Try tomorrow. I don't think that one has the fix in it.

It's tomorrow and the problem is still there.

Not for me it isn't. I've even downloaded a nightly to test it, but not a 64 bit one. Please raise a new bug to describe what's still wrong.
I can confirm that enclosed testcase / original animated demo / is working for me again (in latest build) ;-)
Thanks Marek.
I wonder if Gary is hitting whatever windows issue that the Windows Opt test boxes were running into...?
I downloaded a nightly and checked the reftest. It looks the same to the naked eye.
But as you said in Comment 12, the reftest looked quite different on the windows opt test box -- on that machine, it looked as if the patch never landed.  I'm proposing that Gary's configuration matches that test machine in some way such that he's hitting the same issue.

In any case, whatever that issue ends up being, we should figure it out in a new bug, as you said in comment 18.  Gary: if you could, please file that bug, assuming that you can reliably reproduce the issue in the most recent nightly. :)
Well, I checked it once again and this time on Windows7 with D2D acceleration layer and it is still broken => but on other box Windows XP it is fixed already, as I wrote previously, so the difference can be OS and type of HW acceleration?
Select: Options > Advanced > General > "Use hardware acceleration when

And uncheck the box to disable. If that fixes it you should probably raise a core->graphics bug to track it.
You're right, with D2D disabled it works correctly.
I'll submit another D2D related bug soon...
