Bug Description
Single monitor case - Resolution change or orientation change
Steps to reproduce:
1- Open the Monitors control panel.
2- Choose a different resolution and orientation (we use 640x480 upside down).
3- Press Apply.
4- Select "Restore original configuration" to return to how things were originally.
Expected result:
- Resolution restores, screen rebuilds and is visually identical to how it was before the resolution changed.
Actual result:
- Display is corrupted in various ways. On some systems only the background or parts of it are visible. On others, there's some misplacement of elements. Some others show garbling on all or parts of the screen. On all systems, moving the pointer, dragging windows or generally forcing the system to redraw seems to eventually restore the display to a usable state.

The fix has been committed to unity/3.0. It was verified on an intel system (core i3 330M) and a desktop system with and AMD GPU+ fglrx.

confusing as menu pops up (lp: #735031)
- In a double monitor setup the Unity top panel in the second screen is
cut at the right (lp: #750481)
- Launcher tooltips sometimes don´t show (lp: #769335)
- Menu key should open quicklist for the selected item in the launcher
(lp: #750778)
- unity is spamming ~/.xsession-errors when windows are closed
(lp: #767642)

I tested on 22 affected systems with a variety of Intel, NVidia and ATI/AMD chipsets, changing to i.e. 640x480 and then back to original resolution works fine, with the display rebuilding correctly and the panel showing up without problems.
See this comment for a link to a spreadsheet detailing this and other tests I performed with this update.

So far Unity 3.8.16 seems to solve this problem.
