Horizontal scroll shows differently when using frozen column

[kiwon34]

Hi,
I think I posted the same topic falsely before, so I post this topic again.

Please refer to this example.

And then open a new web site for this url.

I'm testing with 24inch dell monitor, with a resolution of 1920x1080.
Please see the attached image, and you can see that the scroll bar is hidden behind the frozen columns. This happens only when seeing in full screen, and using toolbars.
When I click 'Default layout', the scroll bar is shown normally again. So I assume that this happens only when the grid is initialized. Could you please check this?

It works fine for me. Please mention OS and browser version

I tested on Windows 10, Chrome browser 85.0.4183.83, maximized the chrome browser.

Only occurs at the first time.

No luck so far in reproducing the issue on Windows 10 & Chrome.
