after i have decrease animation speed, the magic lamp effect is the same.

I go on magic lamp effect and i set the animation duration and it work correctly.
Before plasma update, this behaviour was gettable also setting animation speed in desktop behaviour.
Now , i don't know if this is a bug or a simple change desktop effect management . If so, this bug can be close.

reopening

in kwinrc

[KDE]
AnimationDurationFactor=0.25


That shouldn't exist in this file.
It's kwin overriding the global setting; so obviously it won't follow it.

As a fix, just delete that line from that file.

Question then is why that exists. The compositor KCM does still write if it's run outside the KDE environment. Or potentially the user manually figured with it.

Do you remember altering that file?

I'm sure , i didn't touch that file

Ok, I'll keep an eye out for other reports.

In the meantime can you remove those lines, confirm it fixes the issue and let me know if you have any other details reproducing it.

Now, it works well.
I can increase and decrease animation speed perfectly.
Thanks

I had the same issue on Arch Linux running Plasma 5.19.3.
Deleting the lines

[KDE]
AnimationDurationFactor=0.25

from kwinrc file fixed it for me too.

I also have never edited kwinrc file manually.

Another user mentioned this issue on reddit 2 days ago.
https://www.reddit.com/r/kde/comments/hr052j/kde_neon_animation_speed_bug/

David, is the faulty entry in kwinrc a kwin bug, or does some plasma framework component write there, too?

>is the faulty entry in kwinrc a kwin bug

Only kwin would write there.

There is a path that does it, but that's only used if kwin is used outside of plasma and the display settings KCM is opened.  I kept the option there as those users wouldn't have the desktop settings KCM. I can't see how any user could normally hit it.

Hi David,

Just so you know this bug may seem to be here. Animation speed did change using kcm and I also had the line:

[KDE]
AnimationDurationFactor=0.5

in ~/.confg/kwnrc, and I didn't make any manual change to the file.


Operating System: KDE neon 5.20
KDE Plasma Version: 5.20.3
KDE Frameworks Version: 5.76.0
Qt Version: 5.15.1
Kernel Version: 5.4.0-54-generic
OS Type: 64-bit
Processors: 8 × Intel® Core™ i5-8350U CPU @ 1.70GHz
Memory: 15.4 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620

Today my ~/.config/kwinrc file had the 0.5 animation speed written to it.

One thing that I did differently from other users is that I stopped the plasma desktop with logout to restart it.

Maybe for some reason this was the root cause.

I had to delete the 0.5 animation speed line from my ~/.config/kwinrc file to make it back to normal.

My system:

KDE Plasma Version: 5.21.3
KDE Frameworks Version: 5.80.0
QT Version: 5.15.2
kwin Version: 5.21.3
distro: Arch Linux

Which version is this fixed in?

I had the same thing happen to me today with kwin_x11 and was perplexed why only some animations were affected by the slider [KCM -> Workspace -> Workspace Behavior -> General Behavior -> Animation speed], whereas others were not. See examples below.

Animation speed slider affects:
 - Kickstart menu animations
 - Dock/panel animations

Animation speed slider does not affect:
 - Any effect enabled under the [Desktop Effects] KCM


As suggested in other replies, I removed the AnimationDurationFactor=0.25 property-value pair from under the KDE section in ~/.config/kwinrc and the animation speed slider once affects everything as expected.
