Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report with the Request ID and the stack trace, it really helped.

This is a known bug: the chat history ends up with an image block that contains an SVG data URI, in your case the Cursor logo SVG, and the SVG image parser can’t handle it. After that, every new request replays the history with that block and crashes again, so only starting a new chat helps. I reported your case internally and I’ll link it to the existing ticket.

No ETA for a fix yet. If there’s an update, I’ll post it here.

Workarounds for now:

  • Start a new chat, like you’re doing.
  • If you paste something from a browser, Figma, or icons into the chat, make sure it’s plain text and not SVG markup or an image block. It looks like the problematic SVG gets in exactly through that kind of paste.

It seems to break even when I paste a location of a image or a url of an image
