James RussoandClaude Opus 5.5 112ba53302 fix(studio): motion blur falls back for a WebGL canvas Studio reaches first (#7060)
* fix(core): motion blur notices a WebGL canvas the Studio page touched first

When a same-origin host page (Studio) reaches a preview element before the
scene does, for example through a MutationObserver record, Chrome gives that
element the host's prototype. The scene's getContext("webgl") then ran the
host's unpatched getContext, so the canvas never reached the accelerated
canvas set, capture motion blur stayed on, and the WebGL canvas froze during
preview playback.

The tracker now records a canvas in the set of the canvas's own window, and
installs itself in a same-origin parent too, compiled with the parent's own
Function. Cross-origin parents are skipped.

* fix(studio): track accelerated canvases in Studio's window, not the embedder's

The preview runtime no longer installs the canvas tracker in its parent
window. That ran on every preview boot, so any same-origin page embedding
the player got its getContext wrapped, and a host CSP without
unsafe-eval reported a violation on each load. Studio now installs the
tracker in its own window when its Player module loads, and core
exposes it at @hyperframes/core/page-motion-blur.

@hyperframes/studio

Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.

Install

npm install @hyperframes/studio

What it does

The studio is a React application with:

  • Visual timeline — drag, resize, and arrange elements on tracks
  • Code editor — edit HTML and GSAP scripts with CodeMirror (syntax highlighting, autocomplete)
  • Live preview — see changes in real time as you edit
  • Composition inspector — view and modify element properties

Development

The studio is embedded in the hyperframes preview command. To develop the studio UI itself:

cd packages/studio
bun run dev        # Start Vite dev server
bun run build      # Build for production
bun run typecheck  # Type-check

Tech stack

  • React 19, Zustand 4/5 (state management; development uses Zustand 5)
  • CodeMirror 6 (editor)
  • Tailwind CSS (styling)
  • Vite (bundler)
  • Phosphor Icons
