Comment 28 for bug 1605937

I was about to file my own bug, but I'll jump in on this one unless I find evidence to the contrary. I haven't observed spikes in CPU usage (not that I was looking) but wingpanel does steal focus.

At first I thought this was because I use wingpanel in Openbox and Compiz, rather than Gala, but it appears the problem is in wingpanel itself. I note that the panel also tends to keep focus after indicator popovers collapse. The panel itself should probably not gain focus to begin with, ever--only the indicator popovers are interactive elements.

Compiz has a "focus prevention level" setting in ccsm which can help somewhat, but not cure this problem (and it's a sledgehammer-on-a-thumbtack strategy that causes other problems).
