Hi,

We have checked this issue with different devices and browsers and found that it first appeared after the latest Mobile Chrome browser updates (for example similar mobile chromium based browsers like Opera or Edge works fine). Also following jumps is more visible on pages that contain a lot of JS based stretch row scripts of WPBakery builder (for example pages without WPBakery rows like shop page is works normal). Unfortunately since this issue is caused by recent mobile Chrome browser updates we don’t have a quick solution for this, but will investigate it further and if this problem can be fixed from our side via WordPress theme it will be fixed in the next theme update.

Best Regards
