Fix Guide: Sequoia Stage Manager Window Flickering

Symptom: When switching apps in Stage Manager on macOS Sequoia, the side thumbnails flicker, or the active window "jumps" slightly every few seconds.

Why this happens

This is usually a result of a conflict between Sequoia's hardware-accelerated window animations and certain third-party "floating" apps or overlays.
