My borrowing page as solid turquoise with accelerated compositing on.
With accelerated compositing turned on, my Chicago Public Library borrowing page is unusable.
The regular library website (https://www.chipublib.org/) works fine, but when you log in with your library account and then go to your borrowing page (hosted on bibliocommons.com), the entire page turns turquoise. Disabling accelerated compositing fixes the issue and the site works fine.
Epiphany 3.30.2 and WebkitGTK+ 2.22.5 on Fedora 29. Intel Iris 540 (Skylake mobile) graphics.
Presumably, this makes the websites of other libraries unusable since BiblioCommons is SaaS for libraries.
Epiphany issue 595 strikes again.
This is a previous draft that I submitted by mistake along with 193001, which is the one I meant to submit.
The problem only happens on X11, which was what I meant to add.
