I can use, theoretically, any compositor. But other than Xrender turns my laptop in a snail. 
I have some effects selected but none of them works. 
Mine is an Intel Atom netbook, just in case it's useful to know it. 




Cheers, 
Sylvia

 There is. You have to enable Desktop Cube Animation in Desktop effects.

 System Settings > Desktop Behavior > Desktop Effects > Virtual Desktop
 Switching Animation > Desktop Cube Animation.


No, that's what's so surprising.  Under System Settings > Desktop Behavior
> Desktop Effects > Virtual Desktop > Switching Animation

there are only

Fade Desktop and
Slide

as options.

Some more information.  I noticed that on the compositor settings I can only use "XRender".  Every time I try to change it to something else, it moves back.  If I set KWIN_COMPOSITE to Q for Wayland (F 23 uses Wayland, right?), then I'm allowed to choose OpenGL as the renderer, and it doesn't go away.  Then... Desktop Cube Animation option appears -- but just doesn't work.  If I set KWIN_COMPOSITE to O, it refuses to accept OpenGL.

I get this error message in messages:
