Comment 3 for bug 1880397

it looks like it's more an issue of gnome-terminal, because the inner-width is smaller while scrolling. Tested with git output which reaches right border of terminal window, while scrolling it will be wrapped to next line. afair in 18.4 i had modified scrollbars to be always visible (not fading in if cursor is over border)...maybe this bug is older and i noticed it now only in fresh 20.4 without the visibility change (don't remember how i did)
