Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

the animations seem to have been updated with the chat window in the ide and there are two bugs that ive found.

  1. Code change blocks get removed or hidden from the chat if you change chats and back
  2. you can no loonger click on the title of the code block to open the file

Steps to Reproduce

  1. get ai to make a change, switch to different chat, switch back to original chat
  2. get ai to make a change, try and click on the top of the code block (where it says the file name - highlighted in pink dotted area in the second screenshot)

Expected Behavior

  1. the code blocks should stay there
  2. should open the file when clicking on the top bar (has done since ive been using cursor)

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the detailed report with screenshots and the version info. It really helps.

Both symptoms are known and are related to changes in the chat UI in 3.10.17:

  1. The change blocks disappearing when you switch chats is a render bug, not auto-accept. Edits are always written to disk even if the block isn’t shown, and the review should persist when switching chats. The block disappearing is a defect. We’re tracking the issue, but I can’t share an exact ETA for a fix yet.

  2. Clicking the code block header to open the file is also a known regression, tracked separately. No fix timeline yet.

Workarounds until it’s fixed:

  • You can open files manually from the sidebar or via the Review/diff tab, all changes are still there.
  • If the block disappears after switching chats, the changes are still applied to the files, nothing is lost.

I’ll post an update in the thread as soon as we have one.
