Flatpak application does not run and has an invalid icon

[programmablereya]

Is there an existing issue for this?

• I have searched the existing issues

Is your issue described in the documentation?

• I have read the documentation

Is your issue present in the latest beta/pre-release?

This issue is present in the latest pre-release

Describe the Bug

1. Install sunshine_x86_64 from the v2025.118.151840 release.
2. Try to execute the Sunshine application entry added by Flatpak.
3. Nothing happens, and the application entry in the start screen has a missing icon.

Expected Behavior

The Sunshine application entry has the correct icon, and when clicked opens the user's default web browser to the Sunshine web UI.

Additional Context

The Icon= line in the .desktop file needs to have the .svg extension removed to be found (per desktop-file-validate; tested by removing it and verifying that it works).

Unclear what needs to be done to fix the Exec= line.

Unclear what needs to be done to fix the Exec= line.

This is difficult since the UI port for Sunshine can be changed.

[ReenigneArcher]

I put up a PR to address the svg issue. Can you test it once the build is complete?

[ReenigneArcher]

I get these messages in the build log as well. Seems like the tray icon won't work properly either.

[programmablereya]

I can definitely test it - looks like the build didn't produce an artifact with the flatpak, though? Unless there's something that I'm missing about how to get hold of that!

[ReenigneArcher]

@programmablereya thanks! The flatpak linter is complaining about the updated desktop file, hopefully I have satisfied that now. The build is in process again: https://github.com/LizardByte/Sunshine/actions/runs/12856505692/job/35843263796?pr=3561

[ReenigneArcher]

Okay, the lint fails because "flatpak" is in the desktop file 🤷‍♂

https://docs.flathub.org/docs/for-app-authors/linter/#desktop-file-exec-has-flatpak-run

[ReenigneArcher]

I think I have a solution. I will work on it in the next few days.

[ReenigneArcher]

@programmablereya Okay, I think there is progress.

Still an issue with the status icons though. I might need to reach out to the flatpak people on that.

Can you test it? https://github.com/LizardByte/Sunshine/actions/runs/12871812955?pr=3561

If possible can you test both the standard method, and the kms method? For reference this is the new desktop file: https://github.com/LizardByte/Sunshine/pull/3561/files#diff-8c2ac7ddc3d85265d96ca5c2e2f05a27175a062427b4b35d7ea517d68450eb64

[ReenigneArcher]

Actually, this should help with the status icons. I'll get that taken care of shortly. https://docs.flatpak.org/en/latest/manifests.html#file-renaming

flatpak/flatpak#5468

[ReenigneArcher]

New build with icons fixed. https://github.com/LizardByte/Sunshine/actions/runs/12873769335?pr=3561

I will wait until I get confirmation that this works before merging.

(Keep reading - a problem came up while I was writing this)

Beautiful! Icons work perfectly - no need to open the admin UI as long as the tray icon appears. (Presumably not having a valid icon is what was tripping it up and making the tray icon fail to appear before.) Thanks for getting this set up!

... Hmm. Perhaps I speak too soon. A minute or so after being started, it seems to crash. There's no output in the logs that suggests what exactly is going wrong; the exit code is 137, which would suggest it's being killed - but by whomst? There's no log of it being killed by OOM, and that would make little sense unless the Flatpak has a very low memory ceiling - there's still 57GB of RAM open out of 62.4GB, and Sunshine never used more than ~0.2% of it, per htop.

Installing the .deb version on the same machine and running that doesn't cause this problem; it lasts just fine.

The Debug version doesn't work at all (unless I'm misunderstanding its purpose):

Installation complete.

# reya @ kugane in ~ [14:15:50] C:1
