The default on_resize handler (which sets up an orthographic projection)
was being called after your setup() function. The reason this changed
is that in alpha2 and beyond, window events are _only_ dispatched during
a dispatch_events() call (where previously it was ad-hoc).
The fix is to rename your setup() function to on_resize (for convention
only) and replace the calls to setup() with::
w1.on_resize = on_resize
w2.on_resize = on_resize
The attached program implements the fix, and also enables GL_DEPTH_TEST,
which was probably intended ;-)
Cheers
Alex.
