[osg-users] osgQt Material issue

I'm in the process of updating to OSG 3.6.4 and have come across a problem with osgQt. When running the supplied example of osgViewerQt models don't show correctly. It looks like the textures are missing and that lighting is not as expected, but on some models (cow.osg) it appears to be a problem with texture mapping. The same models look fine with the normal osgViewer running 3.6.4. I have attached a screenshot of how cow.osg renders in osgViewerQt. 
The plugins to load the images are correctly loaded in the Qt version. I have played around with the QSurfaceFormat settings but I couldn't see any changes. Is there anything I'm missing or is there something that could be causing this? 
Can others please confirm that the osgViewerQt example is working fine on their side?

My setup:
Visual Studio 2013, compiling in 64bit
OSG 3.6.4 
osgQt master
Qt 5.5.1
