<pre>Not seeing a hang here, but a transparent area where the OpenGL should be
rendered to.
what version of Mesa and Qt were you using?
If you don't mind running an experiment, could you try setting
KNOB_MAX_WORKER_THREADS=4 in the environment before running hellogl2? This
will stop swr from binding threads which might possibly be confusing Qt's
internal threading.</pre>
