Does this stop you from using Cursor

No - Cursor works, but with this issue

Ok. I found how to workaround:

  1. does not work
  2. “Open” works.

Hey, thanks for the report, and it’s great you found a working workaround.

You’re right. If you open a .canvas.tsx file directly from the file tree via double-click or Ctrl+Click, you’ll see the raw TSX source without rendering. To see the rendered canvas, use one of these:

  • Right-click the file and choose Open, like you did
  • Or Command Palette > Open Canvas
  • Or click the canvas card directly in the agent chat

About a Preview button like Markdown has, there isn’t a separate Preview button for .canvas.tsx right now. That’s a feature request. You actually already created it here: No preview button for "Canvas". Let’s keep the discussion there so everything stays in one place.

Let me know if Open ever stops showing the rendered view, and we can dig into it.

This was not the behavior 2 weeks ago. Clicking on a canvas link would immediately open the rendered view. This is either a bug or a behavioral change that was unannounced. I came here to report this issue too.
