use gamescopes --mangoapp argument instead

The behaviour is the same. Mangoapp still stays after shutting down gamescope instance.

Additional info that might be important, I'm on KDE Plasma 6 under Wayland.

Terminal log after clicking close:

gamescope: Received Terminated signal, forwarding to child! gamescope: Received Terminated signal, attempting shutdown! (EE) failed to read Wayland events: Broken pipe

what's the full command you're using?

[stele95]

gamescope --mangoapp -- vkcube

What git version of mangohud and gamescope are you using?

[stele95]

Both are installed through AUR

• https://aur.archlinux.org/packages/mangohud-git
• https://aur.archlinux.org/packages/gamescope-git

[flightlessmango]

Since they are git versions they install whatever is the latest commit when you decided to install, which means only you know what git version it actually is.
With some luck pacman -Q mangohud gamescope should tell us which commit it is
or you can reinstall both packages and check which commit was latest at the time

[stele95]

mangohud-git 0.7.2.rc2.r22.g1e13c38-1
gamescope-git 3.14.2.r97.g41389f7-1

I have a similar issue but with steam:
When I add mangohud &command% to the launch parameters of the steam game, the game remains in memory and running in background (no gui seen).
I use mangohud v0.7.1 in nobara linux 39.

@MacharaStormwing this is likely a completely different issue, please create a new issue for it

I had the same issue on gamescope 3.14.3 from Arch repos. Installing gamescope-git package from AUR fixed stale mangoapp processes. It seems like the bug was fixed in gamescope 3.14.6 or even in the very latest commits.

While using gamescope --mangoapp, gamescope is handling starting and terminating mangoapp, so it should probably be reported there as well if it's still an issue
