What's Wrong?

I am logged in to my remote Ubuntu machine via SSH from my Windows 11 PC using Warp terminal. I try to run the /login command. and see the following:

<img width="985" height="316" alt="Image" src="https://github.com/user-attachments/assets/c7063abd-4e7e-45eb-93d5-56b661560fcd" />

Note that the text appears to be invisible based on me trying to make a selection:

However, either it's not displaying the full URL, or I simply can't copy the whole URL. You can tell because when pressing "c" to copy, the pasted text comes out ending with "...callbac", so it appears to be truncated:

https://claude.com/cai/oauth/authorize?code=true&client_id=[xxxxxx]&response_type=code&redirect_uri=https%3A%2F%2Fplatform.claude.com%2Foauth%2Fcode%2Fcallbac

What Should Happen?

I should be able to copy the full URL to paste into my local browser client

Additional Information

This has always been buggy, I even previously reported a similar issue which I was able to work around. However in its current state, I can not find a workaround, so it makes Claude Code unusable.
