A clear and concise description of what I want to happen

• Termination of the effect on window close.
• The window(s) left open starts to animate.

(First ever post on Github. Please have patience if I have done something wrong!)

Hi, thanks for the clear and concise report!

I agree that such a work-around would mitigate the visual artifact you demonstrate in the video. However, I don't want to implement it, because in my experience, chaining animations like this feels less responsive/snappy. I haven't seen this in other Kwin effects either. Additionally, I'd prefer to keep this effect as simple as is reasonable.

I would guess that the visual artifact you get is caused by the blur effect (see if disabling blur or transparency solves it). Perhaps a better work-around would be to somehow disable blur while the close animation is playing.

Thank you for your point of view! Disabling the blur effect improved quite a lot the overall aesthetic!
