Which model were you using?
_No response_
What platform is your computer?
Kubuntu 22.04
What steps can reproduce the bug?
I'm using tmux (3.2a) with Alacritty. After the recent update, the Codex CLI input textarea where we are prompted to write prompt has a grayish background color. Inside a tmux session that background isn’t applied, but outside tmux it works correctly.
What is the expected behavior?
Background color in the tmux session should work as expected.
What do you see instead?
No background color for the input textarea at all.
