Any ideas how to solve that problem?

[Peter]

I didn't find a solution. Replaced docky with cairo dock which works.

[paxmark1]

Not a solution - but plank is an even simpler form of docky.   

https://launchpad.net/plank
https://launchpad.net/docky    as you can see they have the same maintainers and drivers on both pages

apt-cache showpkg docky versus apt-cache showpkg plank shows the mono dependencies of docky versus the cairo dependencies of plank. 

I am using plank because it is a default of lxqt, however if you wish to use plank in place of cairo-dock you might be closer to your docky experience until someone else finds a fix. 

freenode has a #plank  channel.  A search of docky on OFTC yields nothing. a search of docky on freenode yields one result - #plank.   

I am pretty sure docky should get fixed soon upstream, nice to have choices .  Good luck.
