Reproduce the cursor artefact bug when navigating to the terminal. The issue is old (2018) and the attached gif is broken. Look at the terminal integration code in onivim/oni, likely in the UI layer. Since there are no comments or PRs, first confirm the bug exists in the current version and identify the relevant component (e.g., Terminal.tsx). Then determine if the artefact is caused by cursor rendering or panel transition logic.
