After playing with desktop effects in system settings, the slide transition between my vritual desktop effects is gone.

I did not succeed re-configuring it through the GUI, I tried restoring all settings to default.

To be clear, transition is set to 'slide' but it just switches window, so no animation at all. Other desktop transition* animations are not working either.

Now I would like to check the settings file where this virtual desktop slide transition setting is saved, but I cannot find it.

The only file in .kde/share/config is kdeglobals.

Any hints where this setting is, or what might be wrong with the slide transition, are more than welcome!

Sorry for posting before thouroughly investigating, but now I discovered that all desktop animations broke, including:

- Alt Tab switches without animation
- Show desktop when hovering top left screen corner does not work anymore

I'll investigate further

OK so I found out what happened.

Compositor Settings for Desktop Effects got disabled.

I'm close to sure this happened when changing something under Desktop Settings in the System Settings GUI, I did not enter the Compositor settings.

I'll go try to reproduce the bug..
