Sidebar theming issue with libadwaita + Gradience

[stankovictab]

Is there an existing issue for this?

• [X] I searched the existing issues and did not find anything similar.

Current Behavior

I'm using Gradience to change the look of libadwaita apps on my system. On Resources, the left sidebar when the app is maximized isn't being themed like the rest of the app. Works fine when in a smaller window. It's not an issue with the theme selected in Gradience as far as I can see.

Expected Behavior

The sidebar is themed

Steps To Reproduce

1. Install Gradience
2. Set a theme (in this case it's Catppuccin)
3. Launch Resources

Environment

Flatpak 1.4.0, Nobara (Fedora) 39

Anything else?

No response

Happens on 1.5.0 too.

Hi, in my testing, this issue exists also for Files and Settings, though I cannot exactly reproduce it for Resources since Gradience doesn't seem to work for Flatpaks for me. I think this might be an issue with either libadwaita or Gradience.

I'm using KDE so I didn't notice it on Gnome Files 😅 It must be - I'll close this issue then.

This does appear to be a Gradience issue. https://github.com/GradienceTeam/Gradience/issues/899 There is a temporary fix using custom CSS.
