[Bug] Message display dimmed on initial submission before highlighting on macOS

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.
