>Description:

The latest pixman update breaks display of sized images on (at least)
macppc. I have a system with firefox52 from pkgsrc, nothing else
changed and all working fine. After upgrading base (including X) form
Sep 20 to todays current sized images display with wrong colours in
firefox. This includes the tab title display of most favicons, but also
other images on web pages that are scaled.

Downgrading pixman to 2.2 fixes all issues.
