Comment 4 for bug 1547770

Hello,
I have the same bug. I noticed that when I hover around the top of the screen, my mouse changes shape (I use VNC to connect to my Raspberry Pi). To be precise - when in "captured" mode where I can click around my raspberry it is in shape of a cross, while when hovering over a middle it changes to normal arrow I use on my Xubuntu.
I assumed that arrow shape indicates that I am hovering over window controls so I started clicking at random. It turns out that there are buttons, and that exit full screen is the first button from left. They just are not showing.

I hope this will help to find the bug.
