Comment 1 Vlad Zahorodnii 2022-02-09 12:40:58 UTC 
Those two effects are implemented using different infrastructure. It's surprising that the fall apart is not disabled when there's a running fullscreen effect though, like all other animation effects.

Adding fall apart integration in the overview effect would be very tedious and I'm not sure that it's actually worth it.
Comment 2 saxn 2022-02-09 12:45:20 UTC 
i agree, but fall apart should not apply on overview effect then i guess.

effects/fallapart: Avoid animating windows while there's a fullscreen effect

While there's a fullscreen effect, the fall apart effect should avoid
animating windows as it can corrupt or interfere with the active full
screen effect. This matches behavior of many other animation effects in
kwin.
