Problem description
Mumble is a VoIP application and allows to set an overlay by preloading a couple of libraries prior to launching the game.
Flatpak, however, does not allow to punch a hole in the sandbox for some directories such as /lib, /lib32, /usr. I tried to copy the required libraries in Steam flatpak's directory in order to load the overlay:

cp /usr/lib32/libGL.so.1.7.0 /home/$USER/.var/app/com.valvesoftware.Steam/.local/share/Steam/linux32
cp /usr/lib/mumble/libmumbleoverlay.x86.so /home/$USER/.var/app/com.valvesoftware.Steam/.local/share/Steam/linux32
cd /home/$USER/.var/app/com.valvesoftware.Steam/.local/share/Steam/linux32
ln -s libGL.so.1.7.0 libGL.so.1
ln -s libGL.so.1 libGL.so

I then proceeded by setting the game launch options to:
LD_PRELOAD=/home/carlo/.local/share/Steam/linux32/libmumbleoverlay.x86.so:/home/carlo/.local/share/Steam/linux32/libGL.so %command%

However, the game (TF2) still does not show the Mumble overlay if launched through flatpak Steam.

Any idea of how I can set the flatpak correctly in order to be able to access the right (system) libraries so that I can have the Mumble overlay?

Does this issue reproduce with native Steam
No

I discovered that --device=all most probably does not include --device=shm. I couldn't find anything confirming my suspect in the documentation.
Setting --device=shm to Steam's flatpak solved it completely

also: flatpak Steam must be run after Mumble

regarding Mumble having to be launched before flatpak Steam:
it seems like Steam can't see the connect to the local socket if Mumble is run after Steam (error: connection refused).

If I go into flatpak's bash (flatpak run --command=bash com.valvesoftware.Steam) I notice that permissions on the Mumble's local socket change:

Mumble after flatpak Steam. Only read permissions. Date/time is wrong.

  • flatpak bash:
[📦 com.valvesoftware.Steam ~]$ ls -l /run/user/1000/MumbleOverlayPipe 
-r--r--r-- 1 carlo carlo 0 13 nov 10.24 /run/user/1000/MumbleOverlayPipe
  • host bash:
❯ ls -l /run/user/1000/MumbleOverlayPipe
srwxrwxrwx 1 carlo carlo 0 13 nov 11.58 /run/user/1000/MumbleOverlayPipe

Mumble after flatpak Steam. Works as intended. Full permissions. Date/time is correct.

  • flatpak bash:
[📦 com.valvesoftware.Steam ~]$ ls -l /run/user/1000/MumbleOverlayPipe 
srwxrwxrwx 1 carlo carlo 0 13 nov 12.00 /run/user/1000/MumbleOverlayPipe
  • host bash:
❯ ls -l /run/user/1000/MumbleOverlayPipe
srwxrwxrwx 1 carlo carlo 0 13 nov 12.00 /run/user/1000/MumbleOverlayPipe

Mumble restarted with flapak Steam running. Doesn't work. Full permissions.

The number of hard links of the socket changes to 0. I think this means that the socket was deleted. Date/time is wrong: indeed confirming that it points to the "old" socket and does not update the old one.

  • flatpak bash:
[📦 com.valvesoftware.Steam ~]$ ls -l /run/user/1000/MumbleOverlayPipe 
srwxrwxrwx 0 carlo carlo 0 13 nov 12.00 /run/user/1000/MumbleOverlayPipe
  • hosh bash:
❯ ls -l /run/user/1000/MumbleOverlayPipe
srwxrwxrwx 1 carlo carlo 0 13 nov 12.10 /run/user/1000/MumbleOverlayPipe

Discord

on a similar note Discord, which also communicates with Steam through a local socket, doesn't have this problem. They create links to sockets that do not (yet) exist if Discord isn't running:
