> At a previous company, we were forbidden from using translucency (with a few exceptions) because of the performance cost of blending. There are debugging tools we'd use fairly often to confirm that all layers were opaque.

I feel like a few years back when I still used an Intel macbook i noticed an increase in battery life and less frames dropping (like during 'Expose' animations) by disabling transparency in Accessibility settings.

I think this was after the BIg Sur update.
