epiphany doesn't render some pages
Epic: https://source.puri.sm/Librem5/use-cases/issues/51
When running epiphany on the imx6 board, it doesn't render some pages at all but when you move the mouse around to hover over something clickable, you see the mouse change but the epiphany page stays white.
For example, if you open epiphany from the terminal, and then go to www.weather.com, you see this behavior and the following message is printed to the terminal stdout:
** (epiphany:617): WARNING **: 18:59:26.394: GDK is not able to create a GL context, falling back to glReadPixels (slow!): Unable to create a GL context
