This does not reproduce under r204037. If you believe there is still a problem, please reopen the bug with a revised test case.

Using the attached test case the issue still seems valid in r204165 with debug EFL and GTK builds.

Comment 3 2016-08-05 10:00:42 PDT
Ah! That makes sense. CoordinatedGraphics -> EFL/GTK. It's not used in iOS/Mac. I should have done a better job reviewing that.
