Global environment variables don't work on Linux Mint Debian Edition (Cinnamon)

[MohandL3G]

ProtonShift version

0.9.7

Component

Environment Variables

Description

Global environment variables set via ProtonShift (e.g. MANGOHUD=1, STEAM_GAMEMODE=1) are written to ~/.config/environment.d/70-protonshift.conf, but games launched from Steam don't see them, so MangoHud and Gamemode don't activate.

With help of OpenCode it suggested to me that I use /etc/environment and without quotes "" so it'll be something like:

MANGOHUD=1
STEAM_GAMEMODE=1

Instead of the original ones which are:

MANGOHUD="1"
STEAM_GAMEMODE="1"

Steps to reproduce

1. Enable MangoHud and Gamemode in ProtonShift's Environment page
2. Log out and log back in
3. Launch a game - MangoHud overlay does not appear
4. Use /etc/environment instead
5. Launch a game - MangoHud overlay appear

Expected behavior

Environment variables configured in ProtonShift should be available to all games after a login session restart.

Actual behavior

Global environment variables don't work, so setting something like MANGOHUD=1 doesn't work

Additional context

Can you please fix this and thank you, or at least give us an option to use system-wide setting like "/etc/environment" for example
