Papirus-icon-theme: Icons of Flatpak apps not showing in other applications

[swingcake]

I've noticed that all the icons of Flatpaks do not show in other applications and just a blank image is shown in place.

To understand this better, please have a look at the following screenshots:

(please note that here Spotify is a flatpak, and Chrome is a .deb)

Spotify installed from flathub doesn't have this issue. Did you install from another repo?

[swingcake]

I installed it from flathub.org with flatpak install flathub com.spotify.Client

[SmartFinn]

I have installed with user option. Could you try to install the flatpak package with regular user?

sudo flatpak uninstall com.spotify.Client/x86_64/stable
flatpak install --user flathub com.spotify.Client
flatpak run com.spotify.Client/x86_64/stable

[SmartFinn]

Hmm. I uninstalled the native spotify-client package and now I have the same issue:

[swingcake]

gawd@tushbox:~$ flatpak install --user flathub com.spotify.Client
error: Unable to load summary from remote flathub: Remote "flathub" not found
gawd@tushbox:~$ flatpak remotes
Name    Options
flathub system 

I don't have a clue.

You have to add the remote for your user:

flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

But now it doesn't have sense.

[swingcake]

But now it doesn't have sense.

Sorry?

I just want to say what you don't need to install the flatpak package from a normal user. The icon will be missing until spotify-client deb package was installed.

I mark this issue as upstream bug because it is not related to papirus-icon-theme, but I still don't know what it is related to.

[swingcake]

Ah yes, I didn't see your comment above with the screenshot. This _issue_ is seen with all the flatpak apps. Can you submit this as an issue to them?

[swingcake]

Just noticed that this does not happen with VLC(also a flatpak). So it might be particular to Spotify.

@swingcake Must be an issue with the flatpak packaging of Spotify. https://github.com/flathub/com.spotify.Client It must uses "copy-icon": true in the manifest to fix this issue.

@SmartFinn Is it resolved by flatpak? Why is it closed?

[SmartFinn]

@swingcake because it's not related to the icon theme. I don't see a sense to keep the issue open.
