Lottie animation flicks on safari

hi guys!

my problem is, that my lottie animations sometimes start to flick in safari. the flickering only appears above a certain viewport.

as i said sometimes the flicking happens sometimes not. i already tried to just make the animation not fullscreen, but unfortunately it doesn’t help at all. i also noticed, that the flickering is much worse if i visit the site on a ultrawide display.

if u want to see the problem it appears on this site: www.sterngasse.at
