Hey, thanks for the report. This is a known issue with keyboard input handling in Cursor CLI on Linux, and the team is aware of it.

To help with prioritization, could you clarify:

  • Which terminal are you using (gnome-terminal, konsole, alacritty, etc.)?
  • Does the bug happen all the time, or only in specific scenarios?

I’m using SecureCRT terminal. Happens all the time in the agent, never in anything else.
Looks like someone chose some funky alpha-quality untested terminal display lib and threw it into production with no testing… the scale of the disaster in all terminals is so bad that I really, STRONGLY, suggest you ditch whatever library that was, and go get something else that’s mature and known to work. Terminals are HARD - you can’t just “wing it” !!
