Agent chat window scrolling broken in 1.7.17

Support Bug Reports
1

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The Agent chat window in the latest stable release keeps getting into this weird state where I:

  1. Can’t scroll to the very bottom of the chat to see the last thing that happened
  2. Can’t type in the “Plan, search, build anything” window

Steps to Reproduce

Unclear the exact steps to get into this state. I was at 90%+ usage on the context window w/ Claude 4.5 Sonnet.

Expected Behavior

I should be able to scroll to the end of the chat window and I should be able to type into the textbox to tell the agent what to do next.

Does this stop you from using Cursor

Yes - Cursor is unusable

hi @Alex_Campbell thank you for the bug report.

Could you check and share errors from Help > Toggle Developer Tools > Console

Hey @condor , the issue seems to have fixed itself after closing the agent chat and re-opening it an hour or so ago.

I do see errors in the Console but I don’t see timestamps on them so I’m not sure if they are related:
