I used the above, and tried delaying the pyglet.gl import in a cleaner
way. (Diff -c with your original example is below.)
This convinces me that my original theory is not what's happening
here. With the pyglet.gl imports deferred until the GL context is
current, there is no behavior difference related to dragging the
window. (Something else I did caused the rendering to not show up
until you resize the window. I can't guess what caused that.)
(FYI I also swapped the args of resizeGL to fix a bug.)
Other speculations: maybe pyglet does something which locks the
window, which it normally undoes somehow when it first shows a window
of its own? Maybe it does something which tells the OS window manager
that this Qt window is not the right one to receive some sort of
events? (I think I better stop speculating and wait for the experts to
weigh in.)

P.S. Here's what I tried, relative to your original example code:
