Tim, quickly pressing just D makes it more visible, it might not happen
on every try.

Happens on my T420 with Intel graphics with 2.0.4 (unfortunately upgrade
path is blocked by incompatible dependencies and I cannot test 2.1.x
right now). I happen to be on Linux Mint Debian Edition using Cinnamon
(clone of gnome-shell, uses compositing).

Title:
  White flash when coming back from "Show desktop"

Status in OpenLP - Worship Presentation Software:
  Confirmed

Bug description:
  1. Use dark backgroud for your slide and desktop, black would work fine.
  2. Send something live
  3. Press D repeatedly to see how every time live window is recreated it flashes white.

  Some probably flawed ideas how to prevent this:
  Send first extra short webpage with only background information (when using images it would still take some time and might not work so good)
  Start window minimized and show it after it has finished rendering
  Start window somewhere else and move it to the right position after it has finished rendering

  Or maybe this is not fixable. But at least we gave a thought :)
