Valve released version 3.8.9 Beta of SteamOS to address specific graphical issues in earlier builds. This update targets users who enable screen tearing on their handheld devices.
Patch resolves visual glitches and enhances HDMI audio detection
The primary fix resolves a regression introduced in version 3.8 that caused visual artifacts beyond the expected tear line. Users who rely on the 'Allow Tearing' option will see corrected output with this patch.
- Version: 3.8.9 Beta
- Fix: Allow Tearing Artifacts: Fixed a 3.8 regression where 'Allow Tearing' could result in graphical artifacts beyond the expected tear line
- Improvement: HDMI Audio Detection: Improved dynamic detection of HDMI audio channel count on hotplug
SteamOS 3.8.9 Beta also improves how the system handles HDMI audio connections during hotplug events. The update enhances dynamic detection of the channel count for connected displays and speakers.
The release includes additional stability and security updates alongside these core fixes. Owners can install the beta directly through System Settings on their Steam Deck hardware.
