In my tests and in the official demo, using bootstrap 4 with the theme Redmond (With other themes also happens) a vertical line appears between the columns when moving the mouse or scrolling in the grid … the lines appear and disappear. How can I solve this effect?

Please update which browser / version and OS you are using?
I tested on Win 10 + FF65.0.1 but unable to generate this issue. Can you see same issue on online demos?
i have the same error with firefox
linesĀ vertical black appears suddenly, and suddenly desappear looks like bug in the css. using firefox.
if you use subgrid, the lines only appears before the subgrid content
ej. if the grid have 10 rows and you click to show subgrid content on row 3
the black lines only appears on line 1,2 and 3, the rest rows are no afected.
on crome no problem using win10,
the demo in the site works fine in firefox and crome
