Either that, or you can follow this in order to convert the BG to a pseudo element.

Thanks for the thought, I'd send some sMerit if I had any left.
I had my own back and forth on this when doing the design but went with the fixed background because I kinda liked the effect of the transparent tables overtop the fixed BG, and liked being able to see the BTC in the background the entire time - of course.
I haven't had time to test it yet but I've been intending go the will-change route to improve performance with the background effect.
Not a prob! Yea I like the fixed BG, it's just the GPU performance glitch always throws me off. If you can, definitely take the pseudo element approach
BTW, if you need any help w/ something modular (something you can split off and re-implement w/o too much difficulty), feel free to shoot anything my way.
