Comment 1 kde 2020-09-07 14:36:05 UTC

The animation speed slider does have an effect on the speed of switching the launcher categories, but all other animations stay at the same speed.

Comment 2 David Edmundson 2020-09-07 14:59:11 UTC

What is "all other" window animations?

Can you include your ~/.config/kwinrc ?

Comment 3 kde 2020-09-07 17:12:42 UTC

By "all others" I mean minimizing/restoring windows from the tray, the speed of the wobbly windows animation, the animation when windows appear...

Comment 5 David Edmundson 2020-09-07 18:35:31 UTC

[KDE]
AnimationDurationFactor=0.5


that shouldn't exist.

deleting this line will fix it, but I'm curious how it got there.


Can I have a screenshot of the systemsettings -> display -> compositor window?

Comment 6 kde 2020-09-07 19:18:40 UTC

Maybe it's a deprecated setting that somehow wasn't deleted?

Can I delete the [KDE] line too? On my other machines with KDE Plasma that config block isn't there at all.

Comment 9 kde 2020-09-21 18:10:28 UTC

I've removed this now and everything works as expected.

>[KDE]
>AnimationDurationFactor=0.5

The question remains why this line remained, but I'll close the bug.

Comment 10 Till Schäfer 2020-11-24 00:09:28 UTC

I am observing the same issue here. The mentioned line is also present in my kwinrc

Comment 11 Till Schäfer 2020-11-24 00:18:51 UTC

The line was present on 3 of my 4 KDE installations here. So this must be some common issue. I have to admit that all that installations are quite old though, upgraded from KDE 4 days.

Comment 12 Rind 2021-02-17 00:52:55 UTC

thanks for the solution @David Edmundson 
just for the record: my installation is relatively recent (more or less a year) and this line was present in the file.

Comment 13 David Edmundson 2021-02-17 01:03:36 UTC

We found what was causing that. It got fixed a while ago. 

Any broken instances still remain unfortunately.

Comment 14 Till Schäfer 2021-02-17 08:07:14 UTC

Can we just delete that line whenever the animation time in the kcm is changed? This would be somewhat self-healing. 
Is that setting still in use for something? Otherwise, is it possible to autoremove/ignore that line?
