The fast/events/clientXY-in-zoom-and-scroll.html layout test is failing on GTK and Qt port, most likely after r143068.
Probably failing due to subpixel layout not enabled on those two ports.
We should really try to get all ports to enable subpixel. Having to support both is getting old.
I was checking at the WPE failure and I noticed that the test takes into account that subpixel support might not be available, so it should be a matter of adding a new expectation to GTK+ as well.
