@hez2010 Do you think I can debug by means of screenshots? 😄 If you already run debugger you could review step by step 2-3 method levels and find a root of the issue.

We’ll need a backtrace or a repro outside of Terminal to be sure. A repro outside of terminal would require setting the buffer size to be the same as the window size (no scrollback history)
