webkit-2.28.0 works without problems with x11, but gives an error: "GDK is not able to create a GL context, falling back to glReadPixels (slow!): Unable to create a GL context" ..when used with wayland/weston and epiphany and many web pages appear as a white noise blur. This error is mentioned in https://bugs.webkit.org/show_bug.cgi?id=162598 is it possible that it reappeared?
