Our frozen columns online demo uses static headers and seems to work fine for me under Chrome so I advise that you try upgrading to the latest version (R3 2018 at the time of writing).
You can also using the prev/next buttons for navigating columns as they hide the scrollbar and may be a suitable replacement (you can see how to use them in the second grid in the demo).
If you can reproduce the issue on the demo, can you record a short video to show me how to do that and what I am missing?
