Description

Bug Description
Since the update to 2.1.275 (Sept 18), my submitted message first appears dimmed, blended into the dark background, and only a moment later becomes highlighted. This happens even when Claude is idle and nothing is queued. It looks like the message is stuck or not sent, which is confusing. Before this version the message appeared highlighted immediately. Please restore the previous behavior or add a setting to turn this off. macOS, Claude Code 2.1.277.

Environment Info

  • Platform: darwin
  • Terminal: Apple_Terminal
  • Version: 2.1.277

Research direction

Start by reproducing message submission in Claude Code 2.1.277 on macOS using Apple_Terminal, observing the initial dimmed state before highlighting. Trace the terminal message-display entry point and compare it with the behavior before 2.1.275. Done means submitted messages appear highlighted immediately without suggesting they are stuck.
