Yeah, apologies for the lag with folks on slower devices. That's why we don't have it around for the full season, usually just a week or so. It will probably be removed after New Year's. In the future, maybe I will try implementing a proper user toggle, but for now that's not an option.
It's such a nice touch! I find it so nice to see it flutter down so gracefully ^_^ I'm glad we still have a pretty snowy theme, even after Christmas! Thankfully it isn't lagging for me. Keep up the pretty backgrounds! <3
