Where does the bug appear (feature/product)?
Cursor IDE — Agent / Glass multi-window (split) layout, pinned Skills
Describe the Bug
With “Pin skill” enabled, skills show as buttons above the prompt input. In a multi-window scenario, these pinned skill buttons disappear when the window loses focus and reappear when it regains focus. Because the buttons occupy vertical space above the prompt, their appearing/disappearing shifts the layout each time focus changes, which is confusing.
This is in the same multi-window/focus area as my related report on the side panel toggling on focus change (Multi-window (split Agent): right side panel closes/reopens on window focus change), but it specifically affects the pinned-skill button row above the prompt.
Steps to Reproduce
- Pin one or more skills so they appear as buttons above the prompt line.
- Open a multi-window / split Agent layout.
- Defocus the window (click another window) → pinned skill buttons vanish.
- Refocus the window → buttons return, shifting the prompt area layout.
Expected Behavior
Pinned skill buttons should remain visible (or at least preserve their layout space) regardless of window focus state, so the prompt area does not jump when focus changes.
