I'm on kubuntu with backport and I'm not working on desktop effects, it's a kwine problem.
Please explain what is not working.
(In reply to Martin Flöser from comment #1) > Please explain what is not working. On kubuntu 16.04 with kde 5.8.7 put with ppa backport, it certainly does not work: desktop grid, cube animation, presents windows but i know kwin does not work anything. For example, the desktop grid does not activate with the quick key or even with the sides of the screen. If I have to give commands from terminal to give you more information tell me.
