fix: force layout recalculation on window visibility change#20
Merged
Conversation
macOS can report stale viewport dimensions when restoring a window (e.g. switching spaces, waking from sleep), causing the bottom half of the app to render blank. Dispatching a synthetic resize event on visibilitychange forces a full layout recalculation. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

visibilitychangeevent listener that dispatches a syntheticresizeevent when the document becomes visibleContext
macOS can report stale viewport dimensions when restoring a window (e.g. switching spaces, waking from sleep), causing
100vhto resolve incorrectly. TheResizeObserveron terminal containers doesn't fire because the window size hasn't changed — only the viewport calculation is stale. Dispatching a synthetic resize forces a full layout recalculation.Test plan
