Comment 18 for bug 963093

Screencast attached of trying workarounds in #13.
"Force complete redraw on initial damage" is checked by default.
At the start, you can see flickering and an issue with the top menu shadow.
When "Force full screen redraws (buffer swap) on repaint" is checked, the shadow issue disappears but the flickering remains.
One thing that the video doesn't show is the flickering of the top menu as well as some flickering in the start panel. So it looks like those flickering issues happen in a part of the rendering that is done after Kazam picks up the stream.
