Thanks for reporting the issue @ouuan!

What terminal are you using?

Can you post the same image 1) with the scrollbars and 2) also after running :ScrollViewDisable? This side-by-side would show how the characters are intended to display versus how they are being displayed.

The screenshot is in Konsole, but I can reproduce it in Kitty and XTerm as well.

The screenshot without ScrollView:

I've reproduced the issue outside the context of nvim-scrollview and reported the issue to the Neovim project.
neovim/neovim#17550.

I didn't try it but what if the scrollbar has a width of two characters?

[dstein64]

"I didn't try it but what if the scrollbar has a width of two characters?"

The issue arises from the floating window boundary intersecting with a wide character. This would still be an issue even if the floating window (i.e., the scrollbar) had a width of two cells instead of one cell.
