Valve has released SteamOS 3.9.4 Beta to address several regressions and issues that appeared in the previous 3.9 version, including problems with apps being hidden behind the loading screen and improper screenshot resolutions. The update also includes a security patch that revokes compromised certificates linked to the eMudhra private-key breach, highlighting the importance of maintaining security in the system. Additionally, improvements have been made to audio output and firmware updates, while the hibernation feature remains disabled on the Steam Deck due to ongoing driver issues. Overall, this maintenance release is focused on stabilizing the software and preparing for its eventual transition to the stable channel
SteamOS 3.9.4 Beta Downloads Now With eMudhra Certificate Fix and Regression Repairs
Valve shipped SteamOS 3.9.4 Beta today, primarily to repair regressions that crept into the feature-heavy 3.9 release. The update fixes several genuinely annoying issues, including apps hidden behind Steam's loading screen, screenshots captured at 720p, and a timezone bug that blocked access to Desktop Mode without a reboot. It also adds a security patch revoking certificates tied to the eMudhra private-key compromise, where the breached keys happened to be single-digit numbers like "4." Hibernation work continues but stays disabled on the Steam Deck, and the update points toward 3.9's eventual move to the Stable channel.
