What's Wrong?

Using the terminal in Webstorm on a Debian VM, after updating to 2.1.89, my terminal content is missing. The Claude code header etc is still visible, but none of the content history is. Sometimes using /btw will make it start writing normally (but the conversation history prior to that is not available).

What Should Happen?

It should show the conversation as normal.
