In an amazingly sassily titled update, Valve has fixed the color saturation and fan control problems introduced by The OLED Update yesterday.

      I am a daily user and I have the following issues:

      • Steam Link does not work with Android devices (including Android TV) on Gamemode
      • Sometimes desktop has color errors
        • This is always fixed after a reboot
        • This should be fixed with 3.5.1, but it still happens sometimes
      • Big picture mode does not work on desktop mode
        • I think this is a bug in the newest Steam Beta Client and not Steam OS

      Also, I heard that Steam OS does not boot with custom boot videos via Decky Loader. Custom boot videos via Steam work without any issues.
