YouTube AMD D3D11 Blur Fix

Tiny Chrome extension that removes the backdrop-filter: blur() applied to the YouTube video element. Workaround for blurry video playback on Chrome's D3D11 backend with some AMD drivers — D3D9 renders fine, D3D11 looks soft until the blur filter is neutralized.

Install (unpacked)

1. Clone or download this repo.
2. Open chrome://extensions.
3. Enable Developer mode.
4. Click Load unpacked and select this folder.
5. Reload any open YouTube tabs.

What it does

Injects one CSS rule on *.youtube.com and *.youtube-nocookie.com:

video.html5-main-video {
  backdrop-filter: blur(0px) !important;
}

That's the whole extension. No JS, no permissions beyond the matched hosts.
