Hi Stefan,

I have implemented a very similar, and as simple app with a suclass
of NSOpenGLView. The main window also has some text fields and buttons.

When I move another window in front of my main window, The text fields
and buttons are redrawn normally. The OpenGL view however is not redrawn
and one can see the imprint of the window I am moving in my OpenGL view.

I can't see which method to implement to get the openGL view be updated
when something is moving in front (on top) of it.
Do you have a solution ?

Thank you in advance,
