Ah, that's pretty bad, yes. I was just trying to think of ways to speed up the
blurring once the window is put into position or to at least alleviate the
transition somehow, but maybe it's impossible. Thank you for looking into this
regardless of that and for your quick reply.

That would still produce visual problems. See

You're absolutely correct, this happens because of Wobbly Windows. However,
when I was using the old blur and forced it everywhere with Kvantum  it didn't
have this issue IIRC, it blurred instantly. But that might be because the
blurring method was very different?

Could a workaround be possibly made that detects if a user has Wobbly Windows
on and then implements the gradual blurring that the new screen locker has?
Although this may open other problems, of course.

Blur effect doesn't blur behind transformed windows (wobbly windows effect
transforms/deformates windows). That's because blur effect operates on
rectangular regions.
