Input message disappears while Codex CLI is responding #5538
Description
What version of Codex is running?
0.47.0
What subscription do you have?
Pro plan
Which model were you using?
gpt-5-high
What platform is your computer?
macOS
What issue are you seeing?
When using the Codex CLI, parts of my input message sometimes disappear while the model is generating its response. Lines or segments vanish randomly during processing. In some cases, parts of Codex's output also disappear unexpectedly while it continues to print output. This seems to occur about 20-30% of the time, and I haven't found reliable steps to reproduce it.
What steps can reproduce the bug?
When using the Codex CLI, after I input a message, parts of my input sometimes disappear while Codex is outputting its response. Lines vanish one by one or segments of the input vanish randomly. Additionally, parts of the output generated by Codex may disappear unexpectedly while the rest of the output is still printing. This occurs randomly about 20-30% of the time and I haven't been able to find consistent steps to reproduce it.
What is the expected behavior?
The CLI should keep my input and Codex's output visible while it is processing and generating responses. Neither the input message nor any part of the generated output should disappear; they should persist unchanged until the operation is complete.
