What would you like instead, and why?

I'd like to have no fade, because I don't like anything similar to a morph effect when trying to differentiate similar window previews, and as of now it would work around the issue that the fade doesn't happen only *between* the focused window and the one I'm hovering to. Currently you can see all other windows under the focused and the hovered one, making the effect a bit ugly.

I remember in the past that I requested for that fade effect to be removed, and it got denied.
Will it be accepted now with the accessibility requirements? Without the effect, users with epilepsy can peek at windows without the glitchy fade.

The effect is a bit ugly, but that's in the process of being fixed; see https://invent.kde.org/plasma/kwin/-/issues/288.

So when you wrote "alternatives" did you mean "the ability to just turn it off"?

-Finally. Last time I've reported, I was told it was intentional and that I should use Alt+Tab or something.
-By "Add setting for customizing the effect for window preview peeking" (original bug title) I meant both being able to customize the effect with a variety of fades, and being able to disable it. Notice how all of the Animations menu's settings have a "Nothing" option.

Ok. You can in fact turn it off in both places where it's used. And in fact, in Plasma 6.4.1, it's off by default in the Task Manager, so it's only on by default in the Task Switcher. You can also unload the effect in the KWin debug console to make it work nowhere.
