When I run the program, the window (top right and bottom left) is supposed to be transparent but instead, it is black

A most weird problem has occurred to me a couple of days ago during my exploration of the pyglet package: While window.set_location(x,y), window centering on the screen etc. were working fine, at a certain point when I wanted to center a pyglet window on the Windows screen as usual, the window was totallly off center. See image below.

I am making a game in Python with Pyglet and currently I am tring to involve some menu screens or end screens. I made a class called Screen and the screens (for example GameScreen) inherit from it. The Screen class has a class attribute, s, which is the current screen to be displayed. How am I supposed to assign some Screen object to it?

I’m creating a simple media player. It will be used by non-coders, so I’d like for them to be able to launch it in an intuitive way, eg. by double clicking an .exe

Perhaps the way I am structuring my program just doesn’t make sense , but I would like to use a custom group class to easily plot multiple shapes. I create three shapes with the CustomGroup Class and plot them using the same shader program but with different translations.
