> It's every so slightly slower

in what way? I'd say responsiveness is more important to the desktop than raw performance and from my experience with nearly 2 decades of using Linux desktops, responsiveness has never been great.

If I'm switching between windows whilst encoding a video in the background, the window manager should have instant priority even if it means starving the background task of some CPU time. on GNOME this is quite bad, run a very heavy task (e.g. AI) in the background and the desktop will start to suffer.
