Steam Deck - Regression with Opening ROM in Game Mode

[BlueInterlude]

Describe the bug

When launching ares from Game Mode on a Steam Deck (through Valve's Gamescope, https://github.com/ValveSoftware/gamescope), clicking Load > any system crashes ares altogether.

Rolled back to 144, same issue.

Rolled back to 143, works fine. On 143, clicking a system opens a file browser that then allows me to navigate to a ROM and to select it for play in ares.

To Reproduce
Steps to reproduce the behavior:

1. On a Steam Deck or a system with an equivalent game mode option (maybe reproducible by using gamescope on any Linux distro), add ares to Game Mode.
2. Open ares in Game Mode.
3. Select any system, see ares crash.

Expected behavior

For ares to open a file browser dialog when selecting a system in Game Mode.

Screenshots

This is the file browser that opens on versions 143 and below.

On versions 144 and above, selecting a system crashes ares.

Additional context

journalctl -f shows the below:

Something to look at here: #1946

Is this a self-compiled version of ares? Or are you using the Flatpak/AppImage? or AUR?

[bmsuseluda]

@BlueInterlude do you use the flatpak or appimage?

[BlueInterlude]

Sorry, this is the Flatpak, can compile and see if the same happens.

[BlueInterlude]

Works fine on a self-compiled build, so it is a Flatpak issue. Likely related to the linked PR above, will look into it a bit more.

[bmsuseluda]

ok, just as an info: i could not reproduce it with the appimage either

[jcm93]

Seems potentially complex and possibly an upstream issue in either Flatpak or portals or something else.

For one: I would also report this on the ares Flatpak's repo; since the Flatpak isn't supported by ares itself: https://github.com/flathub/dev.ares.ares

Secondly I'll say: The change to use native file dialogs did not end up being particularly useful, since it turns out that ares's filesystem use is fundamentally incompatible with the current XDG filesystem portal design. So I imagine ares would probably be open to using a non-native dialog again if there aren't any other significant merits to using native dialogs. Personally I'd first want to know the source of the issue and the path to a fix before making such a change though. That also might be in the realm of something that the Flatpak should apply as a patch; probably all TBD depending on what the issue is.
