I know I won't get OSG performance out of it but the reduced Qt integration, Qt5, multithreading, and packaging hassles might make this a viable alternative soon. Qt3D has its own headaches, of course, and is still fairly immature. Maybe I can join a support group for OSG users with a wandering eye.

I have no Qt expertise so can't help with the specifics, but the fact
that you are consider Qt3D because Qt is breaking integration with 3rd
party OpenGL tools is a major red flag.

All the OSG needs is for a Windowing API is for the makeCurrent() to
work then for it to no interfere with with OpenGL state in some
uncontrolled way.  My guess Qt could be doing something with OpenGL
state.

Personally I think Qt is broken in a number of ways.  It's really time
that the computer industry had a C++11 based cross platform Windowing
API so we can all dump Qt,

Robert.
