Steam Frame's first post-launch update speeds up charging and fixes a mic bug

Valve has released SteamOS 0.3.0, the first post-launch software update for the Steam Frame, bringing "substantially faster" charging, a fix for a "garbled audio" microphone bug, and improved controller tracking while haptics are active. The update also improves system stability under high load, fixes the per-app Motion Smoothing "Force Always-On" setting being ignored, and changes the developer playable performance criteria to allow any resolution instead of 1440p.
