I need to call glXWaitVideoSyncSGI() between the update and cull traversals. As
I understand it, this needs to be called with a valid graphics context so I do
viewer.getCamera()->getGraphicsContext()->makeCurrent() and then call
glXWaitVideoSyncSGI() and then call the viewer.renderingTraversals(). However,
the glXWaitVideoSyncSGI call is only working when I use a SingleThreading
model.
Otherwise, glXWaitVideoSyncSGI is returning with an error about a Bad Context.
What am I doing wrong?
