GNOME Terminal scrollbar looks weird on clean GNOME session under Wayland

[AsciiWolf]

When using a clean GNOME session (with Adwaita theme) in combination with Wayland, the scrollbar in GNOME Terminal looks weird (see screenshot 1). The window also looks like it does not have a focus, but it does. Clicking anywhere on the menu bar fixes the focus issue, but the scrollbar still looks weird (see screenshot 2).

Status changed to 'Confirmed' because the bug affects multiple users.

I'm seeing something similar on Bionic when using the Communitheme on Wayland session, where the scrollbar also goes past the bottom of the window. It does not show up when using Xorg. I think the problem also appears under the Ambiance theme on Wayland, but I do not have a screenshot immediately available demonstrating this. The severity of the problem seems to change depending on the theme used.

(I originally reported my issue here: https://github.com/Ubuntu/gtk-communitheme/issues/199)

I'm also now wondering if perhaps this is a duplicate of 1720651.

Same issue for me:
- Community Theme Snap,
- Wayland

I use gnome on xorg on Ubuntu 20.04, and I see the scrollbar sticking out past the bottom of the window also. The scrollbar also sticks out to the right, as in the screenshot posted here. So I don't think this is a Wayland issue, but is an issue with the theme itself. This does not happen with the Yaru theme.
