What's Wrong?
Reposting #19737 literal exact bug because you just ignored it & then closed it without fixing. Retaining the original issue description, but per the multiple follow-up comments, it persists in current ClaudeCode.
On launch, Claude Code’s interactive TUI renders at the top-left corner (row 0) and overwrites existing screen contents instead of starting at the current cursor position below prior output.
On exit, Claude Code does not restore cursor position / terminal screen state, leaving the shell prompt drawn on top of previous output.
This happens in Konsole (23.08.5) but _not_ in GNOME Terminal on the same machine.
Claude used to behave as I expect and only recently (circa 2026-01-19) began exhibiting this behavior.
What Should Happen?
Claude should start on the first row after existing content and or use alternate-screen mode.
