An article detailing the discovery and resolution of a significant memory leak in Ghostty, a terminal application, caused by an optimization bug during scrollback pruning. The fix involves properly disposing of non-standard pages instead of reusing them.
This fix improves the reliability and performance of terminal applications, enhancing user experience.
- The leak was present since at least version 1.0 but became noticeable with the rise of Claude Code.
- Ghostty uses a PageList data structure for terminal content management, which includes standard and non-standard pages.
- A bug in scrollback pruning optimization caused metadata to incorrectly assume that non-standard pages were standard-sized, leading to memory leaks.
