Is anyone else using owncloud and having trouble with Loki? I installed the Ubuntu 16.04 version and as soon as I start the application (and syncing is activated), elementary gradually begins to become unresponsive. I suppose it's doing something in the background (even when it's not currently syncing any files, i.e. checking for file changes or something) which can be seen when the mouse cursor and hover active buttons etc. start flickering rapidly at the same time and the CPU usage of wingpanel spikes (I think) and the system does not respond. If I close owncloud client, problem is solved.
It may be an owncloud bug, but I am asking here because it seems that it doesn't affect Ubuntu 16.04.
