Linux: Proton log files created in home by default

Description

When launching any game through Proton on Linux, no matter if launch is successful or not, a log file is created in the home directory, which considering the behavior of other launchers which use Proton, likely shouldn't be happening. The issue also happens no matter the version of Proton.

Steps to reproduce

• Launch a game in library

Environment

• OS: Linux Mint 22.3
• Hydra installed as .deb

Additional Information

After scouring through Hydra's files, I found a log containing the following:

[2026-03-21T19:50:58.176Z] Launching with umu-run
Command: PROTON_LOG='1' GAMEID='umu-1030300' WINEPREFIX='/home/user/.config/hydralauncher/wine-prefixes/1030300' PROTONPATH='/home/user/.steam/debian-installation/compatibilitytools.d/Proton-GE Latest' '/usr/bin/python3' '/opt/Hydra/resources/umu-run' '/home/user/.jogos/Hollow Knight Silksong/Hollow Knight Silksong.exe'
INFO: umu-launcher version 1.3.0 (3.12.3 (main, Mar  3 2026, 12:15:18) [GCC 13.3.0])
INFO: steamrt3 is up to date

Considering the log, Hydra seems to launch with logs enabled by default, without an option to disable this behavior. After further research, I also found that adding the launch parameter "PROTON_LOG=0 %command%" disables the undesired logging, however it must be added for every single game.
