I'm just talking about the standard KDE desktop. After a while (many days) of running the task bar stops working properly. This is due to some sort of undiagnosed bug but that's really not my boggle at the moment. It's fixed as soon as I log out and in again.
I have to close everything and ongoing processes like virtual machines have to shut down. It's a big pain. It typically means I put up with a bit of flickering for many days.
Is there a way to just reload the desktop without bombing all the running applications?
