zorin-desktop-themes VS blur-my-shell

You can steal it from here. I might also use it nowvafter they finally released a GTK 4 version. The dark purple one looks the best in my opinion.

You can theme your OS to look like Zorin. Their themes are available on Github: https://github.com/ZorinOS/zorin-desktop-themes If you use KDE, it's even easier - someone did exactly that: https://store.kde.org/p/1769479

Other useful info: while researching the gtk2 problem I've come to the fact that many custom themes got problems with gtk2 apps (DC is one example). Probably the default elementary os theme has trouble too and I guess this is correct seeing how it behaves in your case. The only two themes that are working for me is Zorin and Lavanda theme. Maybe you can move the gtk2 folder from eOS 5.1.7 themes to 7.0 and it works. idk. it's only an assumption. the screenshot is from zorin-grey-light theme

Default Zorin OS uses GNOME + Zorin taskbar + Zorin icon themes + Zorin desktop themes.

It was a stepping stone my friend, if you need the theme, here you go: https://github.com/ZorinOS/zorin-desktop-themes

GNOME Extensions : quick-settings-tweaker, appindicator and KStatusNotifier, arcmenu, blur-my-shell, dash-to-panel, forge, gsconnect, just-perfection, show-desktop-button, space-bar, user-themes and vitals

You can install blur my shell extension to modify the look.

if you want blurred backgrounds, the extension blur my shell will work.

Why don't you just look at the source code? https://github.com/aunetx/blur-my-shell

Blur my Shell - Blurs the background in the overview.

dnf install gnome-browser-connector Firefox extension: {addons.mozilla.org} - Resource Monitor • Show system resources in the top bar - User Themes • Custom themes (may break some things) - Dash To Dock • turns the application launcher into a macos style dock - Blur My Shell • make the UI glassy

In my case, I'm using the Blur My Shell extension, so it basically takes whatever background image I have and places it in the overview with a blur effect (though you can also remove the blur completely and just use the extension to set your background as your overview background). By default it will blur a lot of things around your desktop, like the top bar, for instance— just disable anything you don't want; I personally only leave the Overview blur active.
