3.3.0 release changed the canvas max width

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The latest release (installed today 05/01/26) updated the canvas max width to ~768px. I had quite a few canvas’ that featured a wider layout, such as a kanban style representation of a pipeline, which is now being restricted by the max-width.

If this was intensional, would it be possible to make the max-width optional or a controlled setting?

Steps to Reproduce

  1. Create a canvas
  2. On the created canvas observe the restricted width and unused white-space between the canvas and the chat window.

Expected Behavior

Previously the canvas had a smaller margin allowing for a wider UI presentation.
Currently it is restricted to 768 pixels or so.
Expected behavior is to support a wider canvas width either by default or via configurable settings.
