Troubleshooting — Vue
Fixes for Aperveil shaders in Vue: nothing appears, the fallback shows, a value is ignored, or a video does not play.

Troubleshooting
- Nothing appears.
- Give the surface a width and a height: the canvas fills its box, and a box without a height is zero pixels tall.
- The fallback shows instead.
- The browser has no WebGPU, or no usable GPU adapter, or the page is not served over HTTPS (localhost is fine). Keep important content in HTML, outside the shader.
- A value is ignored.
- An invalid value (a mistyped colour, an unknown option, a number out of range) keeps the default and logs one warning in the console. Numbers outside their range are clamped.
- The video does not play.
- A clip on another server must allow it (CORS). A clip on your own site always does.
