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.

Title:

Bug description:
After manually upgrading from 20.04 LTS to 22.04.1 LTS I find that
there is a 1px wide vertical white line on the desktop that appears
whenever an application has focus. It is on the right side of the
monitor, covering the background wallpaper but not the menu.
Workaround: in Displays, change scale to something else than 100% and then
change back to 100%. That white vertical line will stay at the former 100%
window size location until the Settings window is closed. It disappears when
the Settings is closed.
