General

• Fixed a sound crash on session switch on Steam Deck OLED

The Steam Client Beta has been updated with the following changes:

General

• Fixed regression in yesterday's Beta Client which could cause some Steamworks enabled games to fail to initialize.

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

General

• Fixed brief layout shift of elements (one or two frames) when navigating back to the library section.

• Fixed notifications displaying in wrong position in some games.

• Fixed issue that could allow the keyboard to cover the target text area when summoned from a game.

• Improved the download speed of Steam client updates.

• Improved consistency and clarity of download/install/update UI:

  • Byte counts, when displayed, refer to the number of bytes to download.

  • Progress bars and percentages, when displayed, refer to the total progress of the install/update, which includes work before, after, and during the download. The exception is the top (blue) progress bar on the downloads page, which shows the bytes downloaded.

  • Time remaining estimates refer to the total progress of the install/update. These estimates will be very rough at first but will become more accurate as Steam learns more about the performance of the user's network and disks.

• 'Enable Steam Play for all other titles' is always enabled on SteamOS, updated the UI accordingly to stop showing a non functional toggle.

• No longer applying compatibility tool filtering to shortcuts.

• Fixed a rare issue where non-steam Protons could get assigned an incorrect compatibility tool.

Steam Input

• Fix crash when using "Hexgaming Phantom Controller", related to Gyro Timestamp Information.
