Raspberry Pi OS • Re: Icons & symbols missing in GUI applications

So it's only RaspiOS PiXeL which needs something. But what ?

RaspiOS uses a custom theme and icon theme so I would try to change the theme and/or icon theme to something else to see how it goes.

On my custom setup of labwc+xfce I use labwc-tweaks-gtk :

https://github.com/labwc/labwc-tweaks-gtk

I build it from source.

Code:

git clone https://github.com/labwc/labwc-tweaks-gtk.gitcd labwc-tweaks-gtkmeson setup build -Dbuildtype=releasemeson compile -C buildsudo meson install -C build

obs-sudio and mixxx seem to be Qt programs :

https://packages.debian.org/fr/sid/obs-studio
https://packages.debian.org/sid/sound/mixxx

So it might be an issue specific to Qt apps, I'm not sure about this.
