Broken Icons

[canlin-github]

Some icons are missing, see pictures below.

I have both Adwaita and Adwaita legacy icon themes installed and the celluloid I use is the native version from arch linux not flatpak.

BTW I'm on KDE so the icons looks like breeze and I do want to change icon theme to Adwaita. If there is a way to change icon theme for GTK applications in KDE , I'm more than glad to know.

[gnome-mpv]

Try setting the icon theme with GSettings: gsettings set org.gnome.desktop.interface icon-theme Adwaita

Try setting the icon theme with GSettings: gsettings set org.gnome.desktop.interface icon-theme Adwaita

That works, but only temporarily. The problem is it's nearly impossible to make that change persistent. KDE seems to reset that value to "breeze" periodically. Neither setting icon-theme to Adwaita in bashrc nor in KDE's autostart script works.

You really should ask Breeze to either include those icons or inherit them from Adwaita – this also doesn't work on other GTK4 apps with icon themes that isn't Adwaita or inherit from it, and there's no way to solve this from app side without bundling the assets ourself.
