Moving the mouse in and out the notification makes it "out of focus"

Binary package hint: notify-osd

I see a notification. I move the mouse over it and it disappears completely when I enter into the notification area (this could be ok or not, but I'm not reporting this in particular).

Then, I move the mouse not, and the notification appears again, but *out of focus*.

Note that I don't have any desktop effects enabled.

Here I attach two small images, with the notification before and after passing the mouse over it.
