Bug description:
  [Impact]

  Recent libgl-mesa 18.0.5-0ubuntu0~16.04.1 graphics update prevents
  drop down list menu appearing in apps like firefox three line/bar menu
  icon.

  After recently applying updates, left clicking on some application
  menus and icons no longer displays a drop-down menu list.

  For example in Firefox when I left-click on the **three line/bar**
  icon in the upper right-hand corner, the normal drop down list menu
  does not display.  Also the menu drop down doesn't display in
  keypassx.  Further xchat-gnome doesn't even display a window.

  Another anomaly is that my KDE bottom menu bar changed to a dark
  theme.

  
  [Test case]

  Install the update, log in and check that things work normally again

  [Regression potential]

  none, this just prevents a premature feature to kick in

  [Other info]

  I'm using Kubuntu 16.04 on an Intel i7-7700k computer with Intel HD
  Graphics.  I have KDE **System Settings -> Compositor** enabled with:

     Scale method          :        Accurate
     Rendering backend:             OpenGL 3.1
     OpenGL interface:              GLX
     Tearing prevention ("vsync"):  Full screen repaints
     Keep window thumbnails:        Only for Shown Windows

  INVESTIGATION

  After several hours of searching the Internet I found one other case
  of a similar problem.

     Firefox's Menu Bar won't open
     https://support.mozilla.org/en-US/questions/1194760

  The reported solution was to rollback the graphics drivers.

  Because the issues cropped up after applying updates on July 6, 2018,
  I tracked down the list of recent updates with:

     grep -A 2 'Start-Date: 2018-07-06' /var/log/apt/history.log | tail
  -1 >packages.txt

  After some editing to place packages on separate lines, and
  identifying the grahics libraries, I arrived at the following list:

  ------------------------------

  libgles2-mesa:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libglapi-mesa:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libglapi-mesa:i386 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libxatracker2:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libegl1-mesa:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libgbm1:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libwayland-egl1-mesa:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libgl1-mesa-dri:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libgl1-mesa-dri:i386 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libosmesa6:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libosmesa6:i386 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libgl1-mesa-glx:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  libgl1-mesa-glx:i386 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)
  mesa-vdpau-drivers:amd64 (17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1)

  ------------------------------

  To revert to the prior graphic drivers I tracked down the '.deb'
  packages for each of the above packages and downloaded the
  '17.2.8-0ubuntu0~16.04.1' version.

  For example:

  https://launchpad.net/ubuntu/xenial/amd64/libxatracker2/17.2.8-0ubuntu0~16.04.1

  I also discovered that some of these depended on
  libllvm5.0_5.0-3~16.04.1 so I also downloaded the following files:

    libllvm5.0_5.0-3~16.04.1_amd64.deb
    libllvm5.0_5.0-3~16.04.1_i386.deb

  WORKAROUND (ROLLBACK TO PRIOR VERSION)

  Install older versions with:

  sudo dpkg -i \
    libllvm5.0_5.0-3~16.04.1_amd64.deb \
    libllvm5.0_5.0-3~16.04.1_i386.deb \
    libegl1-mesa_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    libgbm1_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    libgl1-mesa-dri_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    libgl1-mesa-dri_17.2.8-0ubuntu0~16.04.1_i386.deb \
    libgl1-mesa-glx_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    libgl1-mesa-glx_17.2.8-0ubuntu0~16.04.1_i386.deb \
    libglapi-mesa_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    libglapi-mesa_17.2.8-0ubuntu0~16.04.1_i386.deb \
    libgles2-mesa_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    libosmesa6_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    libosmesa6_17.2.8-0ubuntu0~16.04.1_i386.deb \
    libwayland-egl1-mesa_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    libxatracker2_17.2.8-0ubuntu0~16.04.1_amd64.deb \
    mesa-vdpau-drivers_17.2.8-0ubuntu0~16.04.1_amd64.deb

  After rebooting, all the issues disappeared.

  For example I was once again able to left-click on the Firefox **three
  line/bar** menu and view the drop down list menu.  Also the KDE bottom
  menu bar retured to the normal "breeze" light grey colour.
