Nautilus on GNOME 45 looks broken

[DannyFatty707]

After upgrading to GNOME 45, Nautilus seems broken with the background's transparency. All other GTK4 apps work fine. For example, Easy Effects (which is on GTK4) works fine with no issues.

I was able to workaround this by adding the following CSS to ~/.config/gtk-4.0/gtk.css:

/* Temp workaround */
.nautilus-window .content-pane {
    background-color: rgb(245, 245, 245);
}

This will at least make Nautilus usable until a proper patch is applied.

It works, but it's just for the light mode. I'm on dark. Can you make one for dark mode?

Update: I've now modified kschat's workaround for Mono's Dark mode:

/ Temp workaround / .nautilus-window .content-pane { background-color: rgb(42, 42, 42); }

You need to replace 245 with 42 for dark mode, or use 245 if you're on light mode.

As you can see here, it looks better now.

In my case the sidebar was also transparent, so I needed an extra selector

.nautilus-window .content-pane,
.nautilus-window .sidebar-pane {
    background-color: rgb(42, 42, 42);
}

Though I'm pretty sure #252525 is the de-facto dark background color and #f0f0f0 the light mode one
