EDIT 2: Sorry guys this whole post was a waste of time. I uninstalled Norton 360 and everything works. This laptop is awesome.

I recently picked up the new Zenbook A16 with the Snapdragon X Elite Extreme, and honestly, the foundation here is incredibly solid. Echoing what most reviewers have been saying, the efficiency of this chip is killer. The machine is remarkably lightweight given its footprint, the OLED screen is stunning, and the raw speed handles intense workflows without breaking a sweat.

However, Windows on ARM is still ironing out some architectural growing pains. While the hardware is top-tier, I am running into some highly specific, annoying bugs. I wanted to document them here to see if anyone has found workarounds, and to share a definitive fix I found for the video playback issues.

The Fix: Resolving Severe YouTube Stuttering

EDIT: This has not resolved the issue. It only worked temporarily.

Out of the box, my machine was struggling hard with YouTube in the browser. I was getting crippling stuttering, dropped frames, and totally degraded hardware acceleration.

It turns out this is a driver-level conflict between the browser's Media Foundation API (which continuously polls for camera hardware in the background) and the current Qualcomm ARM64 GPU drivers. It triggers a cascading failure that disrupts the entire active video decoding pipeline.

How to fix it:

1. Open Chromium browser (Chrome or Edge) and navigate to chrome://flags or edge://flags.
2. Search for the MediaFoundation Video Capture flag.
3. Change it to Disabled and relaunch the browser.

Disabling this flag forces the browser to fall back to the older DirectShow API for camera capture. This instantly stabilizes the browser and completely restores smooth, hardware-accelerated video playback. It does not impact Widevine/PlayReady DRM or HDR for Netflix/Disney+.

The Unresolved Quirks: Touchpad & Backlight

While I managed to divide and conquer the browser issue, the peripheral firmware still feels underbaked. Here is what I am still dealing with:

• Keyboard Backlight Control: The backlight refuses to behave. Sometimes it just doesn't turn off, and other times it won't wake up at all, completely ignoring the MyASUS app settings that dictate it should turn on via touch or push.
• Touchpad Precision & Ghost Touches: The touchpad response is incredibly inconsistent. I am dealing with missed right-clicks, occasional dropped left-clicks, and severe ghost touches that constantly trigger accidental drag-and-drop actions.
• Volume/Brightness Sliders: The built-in smart sliders on the edges of the touchpad are finicky. It usually requires a few deliberate slides or multiple hard taps before the system actually registers the input to change the volume or screen brightness.

I will still keep the machine and hope ASUS rolls out a driver or system fix. The machine is incredibly fast. I do not use it for games, just productivity. All my apps were compatible, except for my Brother printer driver on Arm64. However, installing it from Windows printer and devices menu resolved the issue vs the brother printer suite. I came from the Samsung Galaxy Book pro 4 360, which struggled with everything.
