• fix: Screencast mode: keyboard overlay timeout does not respect the value #238745

2025-01-28.12.48.54.mov

Overview

This PR resolves an issue where changes to the screencastMode.keyboardOverlayTimeout setting were not being immediately reflected in the Screencast Mode keyboard overlay.

Key Changes

• Updated the clearKeyboardScheduler.schedule() method to accept the keyboardMarkerTimeout value dynamically.
  • Previously, the timeout value was fixed when the RunOnceScheduler was initialized.
  • With this change, the updated timeout value is immediately applied without requiring a scheduler restart.

Expected Outcome

• The keyboard overlay timeout in Screencast Mode now updates in real-time when the screencastMode.keyboardOverlayTimeout setting is modified.
• Users will experience immediate changes to the overlay duration without any additional steps.

Testing

• Verified that updating the screencastMode.keyboardOverlayTimeout value in settings.json dynamically adjusts the keyboard overlay timeout in Screencast Mode.
• Confirmed that the overlay disappears after the specified duration for various timeout values (e.g., 500ms, 5000ms).
