Demo

When you exit the overview or desktop grid mode, you may notice how the desktop panel abruptly and without animation restores its transparency, which is a bit off-putting in terms of style. You can see more details in the video.

STEPS TO REPRODUCE
1. Enable transparency mode on your panel (if it is not enabled)
2. Call the overview or desktop grid effect and close it.
3. During the closing animation, you should notice the panel abruptly change its state from opaque to transparent.

OBSERVED RESULT
Abrupt change in panel transparency

EXPECTED RESULT
Smooth change of transparency or in general to make the panel does not lose its transparency during animation.

Comment 1 Prajna Sariputra 2023-12-04 23:19:25 UTC 
Specifically it's the blur effect that's not getting applied in time and/or smoothly, disabling it works around the bug (although naturally it doesn't look as good).

Can confirm.
