We have just shipped an updated Steam Client update to the Stable channel.
Note: This client was re-released September 6th with the following additional changes:
Fixed a case where the steamwebhelper process could experience high CPU usage when certain events were shown in the library tab.
General
Allow changing account while a game is running. In this case, the change account dialog shows a warning that proceeding will close active games.
Added "Ask which account to use on startup" toggle to startup account chooser.
Eliminated "change account" confirmation dialog in most cases. Changing account while Steam is running now brings up the account chooser directly, then restarts as the chosen account.
Steam shutdown now waits for just-exited games to finish cloud sync.
In the Web Browser, the left trackpad of Steam Deck/Steam Controller is now bound to scroll wheel for navigating non-Steam websites.
Fixed issues where some Steam Workshop items were not being updated properly.
Fixed requesting a PIN reset while signed in as a different account restarting with the wrong account signed in.
Fixed a bug where a single pixel line would sometimes appear above the header on the home screen.
Fixed a issue where sometimes uninstalling a game would not remove it from the download queue.
Fixed a crash when suspending/resuming a device after a controller disconnected.
Desktop Mode
Fixed some keys not typing properly in Steam Overlay.
Friends & Chat
Chat messages with suspicious content will now be flagged in group chats. You can report the messages, block the sender, or dismiss the warning by activating the notice.
Steam Input
Make controller configurations that are shared with other devices or unique to a device more clear in the configurator UI and add an option to split Steam Controller configurations so they are no longer shared with Steam Deck.
Remote Play
Improved video color range.
Added support for HDR streaming on Steam Deck OLED.
Added support for AV1 video streaming when using the experimental SteamRT3 Steam Client.
Fixed a case where streaming could show a black window.
Fixed a bug where Remote Devices with Remote Play enabled weren't showing as Streamable.
Fixed video frame being clipped when desktop scaling is enabled.
Fixed framerate drop when using the unlimited bandwidth option when streaming from Steam Deck or Steam Machine.
