Scrolling a page on raspberry stutters

Hi, When I want to scroll the attached json file page on an IOS device it does not smooth scrolling. Is this an ios behaviour or do I need to adjust something? I'm running Open Stage Control server on a Raspberry pi 4. When browsing on a Mac is scrolls fine.

See it in action:
temp.json (35.1 KB)

It's not the raspberry's fault, there might be a bug that occurs only on ios, I'll try to figure it out when I can.

Ok, thanks for your reply!
