Scaling bug OpenGL on macOS Monterey (12.0.1)

On start-up of my app, with an OpenGL context attached, the rendered view is only 1/4 of the window’s size - drawn at the bottom left quadrant. This persists when minimising/maximising and resizing the window in any direction.

Thanks, I’m already able to reproduce the issue and am working on a fix.
