Description Jin Liu 2023-02-21 01:09:28 UTC 
SUMMARY
When minimizing an active window, the decoration changes to inactive color during the animation. This creates a flash at the beginning of the animation, making it less smooth than minimizing an inactive window.

Is it possible that window decoration doesn't change color during the minimzing animation?

Can confirm; the rest of the window goes inactive too.

The issue here seems to be that the window become inactive the moment the minimize animation starts playing, not after it finishes. You can see the same issue in reverse when you un-minimize a window: it's already visibly active during the animation.

I think the current un-minimizing behavior is ok. Otherwise, if the window changes state at the end of the animation, it happens right before my eyes.

Yeah, that actually makes total sense.
