Bug#766898: Render context unstable, turns white or black

[Kai Lüke]

Package: libwebkit2gtk-4.0-37
Version: 2.6.2+dfsg1-1

Regardless whether using Epiphany or
/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/MiniBrowser some sites (which
seem to be embedding stuff?) turn fully white or black (directly or
after some time), some do this as soon as scrolling or hovers appear and
turn back to normal if scrolled up again. Examples are rightnow
planet.gnome.org but also things like Twitter pages (try to scroll).
