Hi,
to close this thread:
after poking around a lot I finally did a clean checkout of the source
-- and voila: it works. Looks like my CraphicsWindowCarbon-header did
not get updated correctly, and so the part of the shared contextIds in
the constructor was not in place -- so context-sharing did not work. Now
everything is fine and happy, even multithreaded. Again, sorry for the
noise.
But one small problem is still there:
I added a glFlush before the copyTexture-call in renderStage.cpp for
debugging purposes. Here are my observations:
without glFlush the rtt-window is white, but the texture gets updated
with the framebuffer, but: the rotation of the cow is choppy (the
animation of the flag is fine and smooth) it looks like an internal
synchronization issue. If I add the glFlush-call again both animations
are smooth.
