Zotero icon in desktop pane is not visible with dark adwaita, XFCE 4.20 and Debian 13

See the image below. Next to the XFCE menu Applications (top left corner), the Zotero task in the task bar/xfce4-panel (4.20.4) is almost not visible (I would expect at least a red Z).
My theme is Adwaita-dark (Gtk3,Gtk2) on Debian 13. I've just installed Zotero, so default settings and no plugins.

We distribute a desktop file in the tarball that specifies an icon. If you've run the set_launcher_icon script properly, you should see the icon in your launcher. Beyond that, you'd have to know how icons work in your desktop environment.

The icon is correctly specified in the zotero.desktop file (I've run the set_launcher_icon script):

Icon=/opt/zotero/icons/icon128.png

That icon exists and is correct. But, independent on the theme, I always see the same square icon

The Zotero version I installed is the one you distribute in the tarball and this issue does not happen with other applications (and also did not happen with Zotero 6)

But the point is that you'll need to debug this yourself. We provide a desktop file and an icon. You'd have to figure out what controls the icons in that taskbar in your desktop environment. Executables on Linux don't have built-in icons the way that Mac and Windows program do — it's entirely external to the executable.

Copying the zotero icon files as follows solved the issue:

cp /opt/zotero/icons/icon32.png ~/.local/share/icons/hicolor/32x32/apps/zotero.png
cp /opt/zotero/icons/icon64.png ~/.local/share/icons/hicolor/64x64/apps/zotero.png
cp /opt/zotero/icons/icon128.png ~/.local/share/icons/hicolor/128x128/apps/zotero.png

Thanks a lot, iagogv! I had the same problem, which had been nagging me for over a year. Copying the icons solved the issue.

For future reference, note that if Zotero has been installed via zotero-deb, the icons are located in /usr/lib/zotero/icons.

All best!

@iagogov
Two notes: first you have a typo (.~/local -> ~/.local) and second is that you may create symbolic links (shortcuts speaking in Losedows terminology) instead of copying. This gives you copies for free. This is possible by replacing cp with ln -s.

Thanks! @KaKooDa. I had thought indeed replacing cp with ln -s, but I didn't test yet.
