SteamDeck SteamOS 3.6.20 Bugs on SD LCD
These are the errors that I have been able to notice on my SteamDeck LCD with SteamOS 3.6.20

• Wifi with a bad signal, it constantly disconnects and loses the Steam session.
• Bluetooth does not work at all.
• Micro Stuttering in all games.
• Most of the time when starting the Steam Deck you don't get any haptics/rumble even in the startup video.

After Reinstalling Steam OS 3.5.7 using the recovery, I got a Working bluetooth and Wifi, but as soon as I updated to the latest version of SteamOS the errors returned.

I confirm the problem. Namely staters in all games that are not available on 3.5 and not working lock fps without vsync in third-party games. It is very global and started with the version 20240318.1000. It is present in all subsequent versions of SteamOS 3.6/3.7. It's about time this problem was fixed @lostgoat

using 3.6.20 with LCD; bluetooth, wifi and haptics are fine for me BUT can confirm the micro stuttering issue in ALL games

Microstuttering - true. Even with 32GB overclocked RAM with dedicated 8GB VRAM - frametime is a sh1tmess.
As for bluetooth or wi-fi coverage - cannot confirm as I didn't noticed anything.
SD: LCD version v2.

I confirm having microstutters on 3.6 SD OLED 512GB. The most apparent cases are GTA IV and Mafia 2 DE. Even after enabling kyber scheduler and self-compiled kernel with 1000hz (from valve sources), it DID NOT stop stuttering.

I must also mention the awful frametime graph present only after updating to 3.6.

I have the same thing, using 3.5.19.
