Actual results: Many images (happens on both png and jpg) have a blu tint. It happens that the image loads fine (colors are OK), but when completely loaded a "blu layer" appears on it. Strangely when the same image is shown more time on the same page not all have the blu tint. Expected results: Images have correct colors as it happened on firefox <= 18. This happened after upgrading to ff 19 on a Ubuntu 12.04 (official ubuntu packages) on a powerpc G4 machine.

Use the tool mozregression to find a possible regression range, see http://harthur.github.com/mozregression/ (ex: mozregression --good=2012-08-01) Reply at: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1130857/comments/7 ------------------------------------------------------------------------ On 2013-02-23T12:43:10+00:00 Oibaf wrote: I did a "mv .mozilla .mozilla_backup", started ff and confirmed the blu images.

No such issue with TenFourFox on OS X PPC, but it's also not using the same downscaler.

This is not really something I can advise on because TenFourFox doesn't use Skia either (only CG). Perhaps Tobias has an idea.

It has been reported on launchpad (https://bugs.launchpad.net/firefox/+bug/1130857 ). The debian PowerPC mailing list also has the problem reported (http://lists.debian.org/debian-powerpc/2013/02/msg00028.html ). Is the patch in mozilla bug 817356 the fix for this?
