Please describe your issue in as much detail as possible:

On Steam Beta client controller doesn't work with this app while on Steam stable client it does, with SLR 1.0 forced just like how Steam Beta client now does that by default.

Tested if this affects Proton titles but no, controller works with them. So possibly somehow that SLR enablement in beta client goes wrong.

STEAM_LINUX_RUNTIME_LOG=1 steam log retrieved:

slr-app225260-t20241018T222524.log

Steps for reproducing this issue:

1. A Dualshock 4 controller and Dualshock 4 config selected Steam Client wide in Controller settings
2. Brütal Legend native build
3. Seeing behaviour change between Stable client while SLR 1.0 forced to game vs Beta client that does it already
