Without root access (or being worried of an update overwriting the changes), this is how I could fix it as a user.
I've placed this in my ~/.config/gtk-3.0/gtk.css file: window.desktopwindow.background:backdrop { box-shadow: none; } Don't ask why it's gtk-3.0 and not 3.20 or 4.0, I have no clue. The "window.desktopwindow" selector is something I've found in gnome- shell-extension-desktop-icons-ng's source. It's a more specific selector than the one in the theme, hence takes precedence over that. Without this selector they would be of the same precedence, and for some reason the one in the theme is used, the one in the user's config is ignored. And GTK doesn't seem to support "!important". This extra selector luckily gives some confidence that the rule probably doesn't have an effect on others. (However, the disclaimer from my previous comment still applies.) In extension-manager toggle the said extension back and forth to apply the change. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1986450 Title: Visual artifact 1px vertical white line right side of the wallpaper To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1986450/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
