[Qtwebengine] QtWebEngine on embedded linux (broadcom mips with OpenES 2.0) displays black rectangles

Hi Guys,

First of all, great work of integrating chromium into Qt. This is huge and we are looking forward to using it on our platform.
As far as using is concerned... we have just compiled the most recent Qt 5.4 sources (including QtWebEngine) and sadly it does not work out-of-the-box.

The websites render with black rectangles in place of images/divs. For example the following HTML:
<html>
     <head></head>
     <body style="background-color: blue;">
         <div style="background-color: green; width: 10px; height: 100px"></div>
     </body>
</html>

renders with blue background body (this is ok) and black rectangle in place of the div (not ok). This happens on all the websites.

Any tips on the possible cause of this behavior? Or where we can start debugging?

Our QPA backend is EGLFS with OpenES 2.0.

Best regards,
Pawel Szlendak
