Public bug reported: When using VGA output, there is a flicker on both screens when resuming from suspend, and/or return to normal screens view when finishing a LibreOffice Impress presentation.
WORKAROUND: Choosing "workspaces" and then choosing any of the four screens solves the issue. Is this a driver bug, and/or a kernel <--> driver bug?
