Note: This update is for the Steam Deck Beta and Preview channels, and includes new features that are still being tested. You can opt into this in Settings > System > System Update Channel.
The Steam Client Beta has been updated with the following changes:
General
Fixed the new controller support panel showing on tools/applications
Big Picture Mode
Add the buttons back to the game launch interstitials rather than relying on the footer buttons
Steam Input
Fix the desktop configuration page being blank when opted-out of Steam Input
Fix for Steam Controller gyro turn rate, and sped up gravity correction. Both were affecting the feel of Gyro to Deflection Mode.
