The Steam Deck Beta and Preview channels just got some nice tweaks including a fix for Black Ops 3 and native games downloading the Windows version instead.
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 the "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 attempt 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.
Steam Workshop
Although not directly related to the Steam Deck, the workshop changes were noted with the Steam Deck client update above and may be relevant for some.
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 downloaded in the game's tooltip on the Downloads page.
