QtWebengine with QtWayland - black blocks seen on browser

I'm using Qt 5.4.1, on ARM A9, running embedded linux, with qtwayland and OpenGL ES. I've successfully compiled (using yocto) QtWebEngine for the platform and I'm able to launch the example browser applications (quicknanobrowser, browser and fancybrowser) .

The issue is that the web contents are appearing as black rectangles. All other widgets/menu of the browser are working fine.

Simillar issue has been already reported and there is a fix for the EGLFS (https://github.com/qtproject/qtbase/pull/4/files?diff=split ). Since my setup is based on the wayland EGL, I'm not sure if porting this fix to wayland EGL would help.
