[Per Johansson <1319075@xxxxxxxxxxxxxxxxxx>]

I suspect I'm affected by this issue too. It started after the upgrade
to Ubuntu 14.04. However, directly after the upgrade the behaviour was a
bit different compared to the bug description. Booting into the desktop
the screen was black except for the line of launcher icons to the left.
Moving the mouse over the any of the launcher icons would reveal the
desktop, but as soon as I moved the mouse back onto the desktop it went
black again.

After some trial and error I managed to switch to "Low graphics mode"
(using unsettings). This reversed the behaviour so that it now behaves
as described in this bug report. The desktop and launcher is works fine
but as soon as I move the mouse cursor over any of the launcher icons
and let it linger until the "tooltip" text with the name of the
application is shown the desktop goes black.

The desktop going black seems to be directly linked to the "tooltip"
text showing. Quickly moving the cursor over the launcher icons  will
trigger the bug. However lingering log enough for the "tooltip" to be
shown, or right-click on an icon to show its menu, will immediately
cause the desktop to go black.

My computer is also equipped with a Intel Corporation 4 Series Chipset
Integrated Graphics Controller.

Title:
  Dark screen when stopping mouse on launcher icons or launching app

Status in Unity:
  New
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu release: 14.04 desktop
  unity version: 7.2.0+14.04.20140423-0ubuntu1.2
  compiz version: 1:0.9.11+14.04.20140423-0ubuntu1
  What expected to happen: showing running apps and/or desktop while launcher or dash is showing at the same time.
