How to debug amissing icon in window switcher

[bin-wang]

Hi everyone! I installed slack using flatpak. In dmenu mode the icon of slack can be shown but it's missing in window switcher mode.

rofi version: 1.6.1
config.rasi:

configuration {
    modi: "window,run,ssh,drun";
    font: "IBM Plex Mono 12";
    show-icons: true;
    matching: "fuzzy";
    drun-match-fields: "name,generic";
    theme: "gruvbox-dark";
}

Below is the result of command rofi -show window -normal-window -theme-str "element-icon {size: 1em;}"

Note that steam is also installed from flatpak but its icon shows just fine.

Output with G_MESSAGES_DEBUG=Helpers.IconFetcher:

❯ G_MESSAGES_DEBUG=Helpers.IconFetcher rofi -show window

The icon files:

/usr/share/icons/Papirus/22x22/apps/slack.svg
/usr/share/icons/Papirus/24x24/apps/slack.svg

/usr/share/icons/Papirus/64x64/apps/slack.svg

Any help would be greatly appreciated.

Just realized that the icon for steam in the window switcher is the default icon rather than the Papirus icon. So maybe this is still a flatpak issue rather than a rofi issue?

The window modi is using the icon from the X11 window, it doesn't look for any file

[bin-wang]

So it must be a flatpak packaging issue then. I see. Thanks a lot!
