Valve released a new version of SteamOS in Preview for Steam Deck, along with a Steam Client Beta for Steam Deck and Desktop Steam also being released. So here's what you need to know.

For SteamOS 3.5.15 that's in Preview the changes are:

  • Improved gamut mapping for HDR titles on Deck OLED.
  • Improved handling of GPU crashes.

You'll need to opt into the Preview update channel to try it: Settings > System > System Update Channel.

For the Steam Deck Client Beta here's the changes:

  • Fixed game news sometimes appearing out of order in game details activity feed.
  • Removed duplicate friend counter on game capsules
  • Added a privacy icon to your own in-game status at the top of the friends list if you are in a private game to indicate the status is shown only to you.

And then finally the Desktop Steam Beta changes:

  • Fixed game news sometimes appearing out of order in game details activity feed.
  • Removed duplicate friend counter on game capsules.
  • Fixed bug which would sometimes cause steam to show UI and take focus if configured to run at system startup.
  • Fixed bug which would sometimes cause Update News window to take focus from other Steam windows.
  • Added a privacy icon to your own in-game status at the top of the friends list if you are in a private game to indicate the status is shown only to you.
  • Fixed a crash when launching a VR game while using SteamVR v1.27.5.

"Fixed Wayland flickering issues" is missing. Oh ye - they didn't. Again.

I'm on Wayland and I don't have flickering at all, could you explain the issue?

Interestingly the 3.6 preview still runs way better on my deck. With 3.5.15 I have random crashes again with gpu errors and the cpu runs way hotter somehow.
Guess I’ll stay with the 3.6 preview

There is no "3.6 Preview", you're likely meaning the extra developer options which no normal person is supposed to use.

Yeah, I mean the main channel beta version. I said 3.6 as the deck reports it this way

Library: You select one title, if you mouse-over other titles, it sometimes just soft-highlights other titles fully or partially (sometimes more than one) and flickers those highlights in-out with mouse move. Sometimes it even manages to show the game-page of the flickering title you did not mouse over - even without selecting the game you are currently mouse-overing. The faster you move over your library titles, the more often it occurs, and the more extreme it gets. If you move out of the selection and just mouse-over "maximize" in example it also soft-highlights the last title you did hilight over and flickers. If you resize the window to a smaller size it happens less.

Library Game-Page: The game screen is not properly loaded, respectively, instead of the title picture of the game or even sometimes the whole window it is transparent showing the window you have below.

That changes as soon as you manually trigger a full window redraw (resizing, taking a screenshot) to the correct behavior, until it occurs again. Running OBS fixes this too, so I guess it's something to do with how redraws are conducted.

May be related to Nvidia drivers though, but it really is a ugly issue happening often enough (like every 5th click). Since this only happens in Steam and with no other application, I'd guess whatever they use (their own toolkit?) is not properly handling at least on Nvidia+Wayland.
