I wonder why I haven't heard about it, but damn, the stage manager implementation is awful. I don't mean the design, that's a matter of taste, but there are constant glitches, windows jumping away from the mouse (sometimes outside the screen) and, my absolute favorite, window management becoming more buggy after turning stage manager off: The window movement would lag behind the mouse and when attempting to resize the window would violently wobble and scale to wildly different sizes.

I'm on a dual monitor, dual resolution setup with the monitors not perfectly aligning, I guess one or more of these things could have something to do with my experience. But I'm pretty sure that's a setup they support and should've tested and more than 0 people should have run into these issues during the beta phase. So what's the excuse? If stage manager is a preview of the quality of new features the future looks bad.
