Glad you found out and thanks for sharing !

What was the additional file you had wrong ?

oh it was

libqxcb-glx-integration.so

in

/usr/lib/qt5/plugins/xcbglintegrations

dir
This .so is new addition since 5.5.
may ppl has issues with nonworking OpenGL due missing this library after upgrade to 5.5 but forgotten to install this lib. (there is also EGL version of this lib btw)
It is usually because packagers are frequently putting them the into separate package called usually xcbglintegrations plugins or similar.

btw: I'm really impressed in increasing quality of qt regarding building process.
