We have just shipped an updated Steam Client to the Preview/Beta channel.

General:

• Fixed a regression that caused non-Steam games to fail to launch.

• Fixed the onscreen keyboard not working the first time it is invoked on desktop.

Remote Play:

• Improved color accuracy when streaming an OpenGL game.

We have just shipped an updated Steam Client to the Preview/Beta channel.

General:

• Fixed the Recordings & Screenshots dialog not showing all games that have related screenshots in the game filter dropdown.

• Improved the text layout in achievement notifications when the name, description or both wrap across multiple lines.

• Fix some cases of header/footer flicker and invisibility during the first seconds after waking from sleep.

• When waking from sleep with a game running but the account now playing elsewhere:

  • Provide an option to exit the local game.

  • Go back to sleep if there is no input for 60 seconds.

• Fixed issues with trackpad typing if the trackpad is touched while the onscreen keyboard is opening

Steam Input:

• Improved the consistency of trackpad sensitivity between Steam Deck and Steam Controller

• Fixed cases where the Virtual menu modes could show the wrong activation type if it was created in the standalone menu vs from a controller source

• Implemented a version of the "Reorder Controller" dialog for Steam Input API games. Note - this disconnects the controllers temporarily so older games which do not handle hot plugging properly can lose controller input

• Additional polish for the multibinding page

• In the desktop UI overlay the desktop config will now be applied. For most gamepads this will not be a difference in behavior because they have a blank desktop config, but Steam Controllers or devices that have setup a custom desktop config will have mouse input to click on things in the overlay.

Remote Play:

• Improved color accuracy when streaming from a Windows computer

• Fixed the mouse cursor when streaming from Linux using the SteamRT3C client

• Fixed a capture lockup when streaming from pipewire on Linux and SteamOS

• Reduced Pyrowave latency when streaming from pipewire on Linux and SteamOS

• Added the -pyrowavestats command line option to log Pyrowave encoding performance

SteamRT3 Experimental Beta

• Fixed Steam overwriting PATH, LD_PRELOAD, and LD_LIBRARY_PATH variables when launching games.

This update is for the SteamOS Beta and Preview channels, and includes new features that are still being tested. You can opt into this in Settings > System > System Update Channel.
