Visibility:hidden used when creating iframe does not solve blinking scrollbar, because visibility:hiden only hides element, but its dimensions are reserved.
You should use display:none style, or at least assign ID or any ID-like class to silent-refresh iframe (ideally the name should be editable in the client settings), so we can use styles to properly hide it. This applies to all "invisible" iframes you use.
