Update Pyglet from 2.0.9 to 2.0.18 pip install --upgrade pyglet Then issue #14 occurs

[andrewgait]

I'm seeing this problem too (Windows 11, using anaconda for virtual environment).

A quick google suggests that the problem might be a graphics driver issue, but as @JamesDownes5 says, upgrading pyglet to 2.0.18 fixes this issue, but then the other issue occurs.

[JamesDownes5]

Apparently this is a graphics driver issue: https://github.com/psychopy/psychopy/issues/1579 But there's no way anyone's downgrading their graphics drivers on windows just to get this working. We'll just have to find what the difference is between Pyglet 2.0.9 and Pyglet 2.0.10 and implement the fix

I fear you are correct. The good news is that, given it displays at least something correctly, we're probably not dealing with fundamentally incompatible bits of software but it might well involve a major refactor.
