Buggy & Laggy Mission Control, Spaces, & Stage Manager in MacOS 27 Golden Gate? Try These Tips

Some Mac users who have recently installed MacOS 27 Golden Gate have noticed an unusually laggy and buggy experience with Mission Control, full screen apps, and Stage Manager.
Impacted users complain of a slow lag, delay, or stutter before entering Mission Control and/or Stage Manager, or swiping between spaces or full screen apps, flickering thumbnails, black or empty spaces when switching between them or when using multiple displays, window thumbnails failing to draw, frame rate issues, animation issues and stuttering, or even a complete lack of animations and a sluggish redrawing of the screen elements. These problems may be due to an incompatibility, or perhaps even bug in Mission Control and/or Stage Manager, or even WindowServer, as these features are reported to have been quite smooth and consistent visually for most MacOS users until they installed MacOS 27. It’s also conceivable that these type of visual hiccups and performance issues will resolve themselves over time as MacOS Golden Gate has finished indexing itself and performing background tasks, in a similar way that sometimes just waiting can help to resolve battery life issues experienced with MacOS 27.
If you’re experiencing issues with Mission Control, swiping between full screen apps and spaces, using Stage Manager, and interactions within these features, you’re not alone, and there may be some tweaks and adjustments you can make to improve the performance of these features.
