Scene transition has wrong colors on macOS

[achimmihca]

Actual behaviour

The scene transition on macOS (Big Sur 11.7.3) uses wrong colors. Seems like the shader is messing up something. The effect can be seen in the logo, so it is not just the buttons.

The wrong colors depend on the current theme, maybe they are inverted.

Expected behaviour

Scene transition should use the same colors as before.

The issue also occurs on iOS 16.3
