Bug Report – Stitch UI Generation Issues

Issues Identified

1. UI shows raw code blocks

  • Description: In some UI generations, instead of rendering components properly, raw code (like JavaScript loops or JSX) appears directly in the UI.
  • Impact: This breaks the visual fidelity and confuses the layout logic.

2. Black blocks + disjointed layout

  • Description: Sometimes the generated UI contains large black areas, and all components and text are pushed far down the page (3–4 scrolls below). It feels like a static HTML dump with broken CSS.
  • Impact: Layout is unreadable and not usable for design refinement or export.

3. UI generation hangs or fails

  • Description: Occasionally, Stitch throws an error:

“Something unexpected happened, and Stitch couldn’t complete your generation. Please try again in a moment.”
The UI then continues loading indefinitely without success.

  • Impact: Blocks productivity entirely, forcing me to start a new chat

@Wydoinn Thanks for your feedback. We are tracking the 1. UI code blocks and 3. Design generation failures issues. I will file a bug for 2. [UI] issue of black blocks.
