Public bug reported:

Ubuntu Cosmic.

QtWebEngine 5.11.1

QtWebEngine doesn't work under wayland since it can't find eglGetProcAddress 
call.
Instead it starts spamming 10's of thousands of loglines per second.

This is an issue since qutebrowser doesn't work under native wayland
while this bug exists, so web-browsing seems to be use software-
rendering instead.

[487:518:1113/101024.893528:ERROR:gl_surface_qt.cpp(230)] eglGetProcAddress not 
found.

simple qml which recreates this issue under wayland is attached and can be run 
by:

<starts spamming and doesn't work>

Corresponding upstream / QT Bug:
https://bugreports.qt.io/browse/QTBUG-68479
This has been patched by QT and as far as i've understood it should be 
available in 5.11.2
