User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/17.0 Firefox/17.0 Build ID: 20121113065533 Steps to reproduce: I've applied simple 'relief' filter to the gold text, see the attached test case. Actual results: There is greenish aura around this text. Expected results: No aura is displayed. It seems to be a regression as it looked much better in previous versions.

Confirmed on Mac too. I suspect this is due to painting text with subpixel AA into the surface to be filtered. Maybe we should not use subpixel AA in filters, masks, etc.?

Is there any temporary work around for this?

seem to be an similar problem as is in Bug 929451 https://bugzilla.mozilla.org/show_bug.cgi?id=929451

I don't see the problem on Linux for some reason. Let me know if these builds fix the problem: https://tbpl.mozilla.org/?tree=Try&rev=58c0cb34ba6e

Er, these builds: https://tbpl.mozilla.org/?tree=Try&rev=c74f9922d3d4

The patch doesn't seem to make any difference as far as I can tell. I can see the greenish aura with/without it just the same.

All is not lost as I see where the patch is going and it just needs this too. If you apply this and your patch everything displays correctly.
