Hello,
1) Try to disable all the third-party plugins, that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins , clear all cache, check how the scroll works then.
2) Theme Options > Header builder > Top header > Content Zoom (%)
or add the next code in Theme Options > Theme custom CSS:
.header-top .et_b-icon {
font-size: 21px;
}
3) As I can see, you are using WPML, so contact the support of the plugin to get assistance
