Styling Bugs Specific to iPhone X?

I was doing some testing and when using a colleagues iPhone X I saw some crazy looking bugs, mostly to do with the CSS (i can explain further if asked) - functionally it all works though.

I did some experimenting and I don’t see this problem in the rig, on my own device (a Sony Xperia XZ), or on another IOS device (iPod touch 6th gen).

Before taking a deeper dive into this I was wondering if anyone else had experienced similar problems?

My (released) extension seems to work ok on my iPhone XS Max

Are you using react-redux?

No. Straight JS/HTML/CSS

Ok thanks for the info, it helps because my current theory is that it’s not enjoying the react elements.
