Blink, flash, glitch depending on a browser on a mobile vertical

Hi, help needed really bad

Hero screen blinks on mobile. I’ve read somewhere here this might happen because of many animations within one section. Looks like the glitch occurs at the moment the slide changes. Any idea on how to get this fixed? Without removing animation?
