Jarring thumbnail fade animation

Tooltip thumbnaikls now have a jarring fade animation that didn't exist in previous versions of plasma. This isn't a problem if you invoke only one tooltip, if you invoke one and move across the task manager to show more, the animation becomes jarring. Since the tooltip fades in only for the first one invoked, the thumbnail should also fade only for the first. A video is attached showing the issue.

I'm afraid this intentional, to disguise the otherwise abrupt disappearance and appearance that we were not able to address.

If anyone can submit a merge request that satisfactorily addresses it, that would be great. Until then, the fade has to stay.

I figured as much. Is it possible, however, to reduce the fade time a bit? Seems too slow as it currently stands.
Comment 3 Nate Graham 2022-08-31 13:29:43 UTC
Sure, that's reasonable.

applets/taskmanager: speed up appearance animation for PW thumbnail

LongDuration is too slow and slows down user interaction. Change it to
shortDuration.
