In a new installation, just 2 days ago, of Antergos with KDE, yesterday I installed Docky to launch the applications, and everything worked perfectly, with its animations and intelligent hiding.
Today when turning on the PC I find that these animations no longer work and that it remains fixed, with an opaque background that can not be changed.
Nor does the effect of wobbly windows that I had on desktop effects work.
I know the Docky dock needs to have those desktop effects activated, but I do not know how to activate them, nor why they were disabled.
The only thing I did was an update yesterday of just two packages that I do not remember what they were.
