Strangle blue background color

Upgrading from 3.18 to 3.19/3.20, gtk displays emacs as having a strange blue background color. This is an issue regardless of my emacs init file.

    gdk: calculate pixel color shift and precision lazily
    
    This gets rid of the decompose_mask utility entirely and simplifies
    backend code.

This is marked as fixed but I'm still seeing it with gtk 3.20 on Arch (on X and wayland)
Comment 3 Emmanuele Bassi (:ebassi) 2016-03-26 14:40:47 UTC 
It's fixed in master:

https://git.gnome.org/browse/gtk+/commit/?id=8206b824fa3cba5cbc7ddec0a1ccec7828f37dc5

Please, try a GTK build with that commit.

Thanks Emmanuele, I've built a package from master and it's fine. Having the commit id in bugzilla makes it much easier to check which version the fix is in.
