Valve Just launched a Steam Deck Client update for the Stable channel. Here are all the changes and fixes that come with this new update.
General
Reduce the amount of black screen flashes that happen when opening the Steam interface while playing a game with a custom screen refresh rate setting.
Replaced Nearest scaling mode with Pixel, a pseudo-bandlimited filter for upscaling pixel art to non-integer factors without introducing aliasing. Integer scale factors will still be Nearest.
Fixed "Friends who Play" section not refreshing until the client was restarted
Fixed a crash in "Call of Duty: Black Ops III" when switching maps.
Fixed situations causing the Steam client to only download the Windows version of a title and later attempting to run it without Proton.
Reset the HDR Visualization setting to None for all users.
Moved the HDR Visualization setting from Display->Advanced to Developer settings.
Adjusted the recent games page header so that it's visible when changing selection.
Fixed left trackpad haptics triggering at wrong pressure for Steam Deck OLED.
Fix "View Additional Artwork" button not properly showing content on soundtrack details pages.
Steam Workshop
Re-designed the Workshop subscriptions list (accessible from Game Properties). It now includes the ability to sort by subscription date, last updated, size, name, and load order.
Added ability to change the local load order of Workshop item subscriptions.
Added ability to set the local order based on any Workshop item dependencies (must be set on the Workshop items themselves).
Added ability to disable Workshop item subscriptions, which will hide them from the game.
Added the ability to filter the Workshop subscriptions list by tag name. Use the same search field for filtering items by name.
Show the name of the Workshop item being download in the game's tooltip on the Downloads page.
Added functionality that allows swapping the items in your subscription list quickly using collections:
Added ability to save the filtered list of items to a new or existing Workshop collection. This will overwrite the contents of the collection with the contents of the list.
Added ability to overwrite the user's subscription list to just the contents of a Workshop collection.
Added ability to add items from a collection to the user's subscription list.
