Opening file windows

[Guest]

I'm having a bit of a problem when opening various windows. For example, when I insert a flash drive a window opens showing what files are on the drive. When I click on a file to open, sometimes it opens in front of the first window and sometimes behind it. No rhyme or reason.
I've noticed that the same thing is true with programs. If I have, say, Firefox open and click on the icon on the panel to open LibreOffice, sometimes Libre will open in front of Firefox and sometimes in the background. Again, you pays your money and you takes your chances as to which way it goes.
I'm using Kubuntu 14.04 with the KDE 4.13 desktop. Checking compizconfig, auto raise is turned on.

You installed Compiz? Why? It isn't required, as the native Desktop Effects are more than sufficient.

I noticed too, occasionally, and I don't know why, but since it doesn't happen often, I suspect it is a problem that will be fixed in due time. Make another generous contribution to Kubuntu; perhaps the problem will get closer to the top of the list of things to do for free.

I still keep Kubuntu 15.10 in my computer, just because I think it's pretty, and because I have faith they will work out all the bugs. Calling it not perfect is generous, but still I love to watch its growth. I love "Desktop Effects" excepting in the latest version where it currently should be named "Desktop Defects", perhaps. No offense guys, but it is going to be a work-in-progress for a while.
