The scroll performance on your site is lagging quite heavily on my computer. Seems to be all the nearly-invisible backdrop blurs, because when I zap those from the stylesheets it perks right up. Not all the way up, but the majority of the way up.

Yes, there is a semi-transparent background overlay. It works fine on my devices, but I will definitely investigate this issue and optimize the CSS.
