The kernel scheduler will try to keep it on one core. Migrating it
from one core to another is inefficient, in that it has hot memory in
the L1 cache which is local to a core. Moving it means it needs to
rebuild that.

http://www.compiz.org/ tells you more about what compiz is.

It might be enough to log out your desktop session and log in again,
so it starts a new desktop.
