Were there animations in the previous Plasma versions?

yes, the panel is supposed to slide in and out in a similar way to Krunner or the Windows taskbar

Just the animation is missing, or the whole hover effect entirely?

whole hover effect, I could've phrased that better
(I should stop writing bug reports when I'm too tired to think)

This is kinda strange. I did encountered this bug during development, but then specifically wrote a workaround to avoid it. Could you confirm, that if you disable animations in the Breeze decoration settings, the hover effects works?

I'm sorry I don't see any option to disable animations in the Breeze decoration settings
Comment 7 Mikhail Zolotukhin 2020-09-19 16:57:57 UTC 
Huh? Indeed this setting is gone in the last dev iso. This explains why it is not working. The hack I used was the to temporary disable animations setting and then enable them for the moment the button is drawn.
Comment 8 Nate Graham 2020-09-21 04:27:33 UTC 
Yep, I can confirm the whole hover effect is missing. However disabling animations with the global speed slider in System Settings > Workspace Behavior > General Behavior does not fix it for me.

What if you disable animations globally and then change decoration theme back and forth?

No dice, sorry. :)

Hmm, for me, it worked.
Comment 12 Nate Graham 2020-09-24 13:46:03 UTC 
Oh, that's good news. Probably my setup is somehow unreliable then.
