# HyperFrames v0.8.43

By Steven Van · 2026-09-16

Portrait compositions render in full, a new lint check catches size drift before render, and render telemetry gets more detail.

[HyperFrames](<https://creatorstoolbox.com/resources/hyperframes>) v0.8.43 fixes a rendering bug where a portrait composition (for example 1080x1920) built in a project scaffolded landscape only rendered its top 1080px, with page background showing below. Portrait compositions now render the full frame.

- A new **root\_dimensions\_mismatch** lint warning fires when a composition root's data-width/data-height disagree with the html, body CSS size or the viewport meta, so the drift shows up in lint and check before a render. It can also fire on sub-compositions saved as full HTML documents even though the parent composition sizes them correctly; that false positive is slated for the next patch.

- Docs search now shows the correct catalog source file name instead of *\[object Object\]*, after a [fix](<https://github.com/heygen-com/hyperframes/commit/7b5fdb1ad28347272d235edea7aa6a9c762d5e1c>) to how "Source" accordion titles are generated.

- Render telemetry gains detail: render\_complete events now include a per-element-tag count plus aroll\_video\_count and heygen\_video\_count, and render\_error events add error\_name and failed\_stage\_code.
