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

SteamOS 3.5.3 Preview: The LCD Update
Note: This update is for the Steam Deck Preview channel, and includes new features that are still being tested. You can opt into this in Settings > System > System Update Channel.
- Fixed a regression with color management sliders
- Fixed a fan control regression
Sorry about this, but are we sure the fan problem was solved for LCD Steam Deck in spite of this update? I updated only last night and today my fan seemed unusually noisy, either when I’m simply browsing the OS or when I’m playing a relatively undemanding game like Hollow Knight.
