This appears to be the same bug I am experiencing.

Graphical regression

Kubuntu xenial/16.04.4
Intel HD Graphics 530

Symptoms:
* Under KDE Plasma 5, the blur effect for most widgets with a transparent 
background is not rendered. Instead, an opaque background is rendered.

* The on-screen display provided by KMix when adjusting the volume using
keyboard hotkeys is not rendered. Instead, only its background blur
effect is rendered.

* In some applications, some pop-up menu widgets do not render (they are
invisible). For example, in Clementine, the drop down menu on the Stop
button does not appear visibly when summoned, the main menus do not
appear visibly when summoned, and the right-click menu does not appear
visibly when summoned. In Firefox, the all-in-one "hamburger" menu, as
well as other pop-ups from the main toolbar, do not appear visibly when
summoned. However, the main menus (accessed by pressing Alt, if hidden)
do appear. In the print dialogs in Okular, the drop-downs for "Page set"
and for printer-specific settings do not drop down. (Selection has to be
made by blindly scrolling through options using the arrow keys.)

As remarked by others, menu and volume OSD visibility is restored by
using XRender instead of OpenGL 3.1, but there is no background blur
effect and the background of Plasma widgets remains opaque.

For completeness, here are the results of my investigation into which
packages were causing the problem. This seems very similar to what has
already been said.

The symptoms appeared after upgrading some packages using the package
manager (aptitude).

The following subset of the package upgrades that took place appear to have 
caused the symptoms, since downgrading only these packages eliminates the 
symptoms:
package / old version / new version
libwayland-egl1-mesa:amd64 17.2.8-0ubuntu0~16.04.1 18.0.5-0ubuntu0~16.04.1
libdrm-common:all 2.4.83-1~16.04.1 2.4.91-2~16.04.1

libdrm-amdgpu1:i386 2.4.83-1~16.04.1 2.4.91-2~16.04.1
libegl1-mesa: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
libgl1-mesa-dri:amd64 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
libsensors4:i386 [not previously installed] 1:3.4.0-2

There were other package upgrades at the same time, but downgrading only these 
packages eliminated the symptoms. There are no symptoms with the following 
versions:
package / version downgraded to
libwayland-egl1-mesa:amd64 11.2.0-1ubuntu
libdrm-common:all 2.4.83-1
libdrm-dev:amd64 2.4.83-1
libdrm2:amd64 2.4.83-1
libdrm2:i386 2.4.83-1
libdrm-intel1:amd64 2.4.83-1
libdrm-intel1:i386 2.4.83-1
libdrm-radeon1:amd64 2.4.83-1
libdrm-radeon1:i386 2.4.83-1
libdrm-nouveau2:amd64 2.4.83-1
libdrm-nouveau2:i386 2.4.83-1
libdrm-amdgpu1:amd64 2.4.83-1
libdrm-amdgpu1:i386 2.4.83-1
libegl1-mesa:amd64 11.2.0-1ubuntu
libgl1-mesa-dri:i386 11.2.0-1ubuntu
libgl1-mesa-dri:amd64 11.2.0-1ubuntu
mesa-vdpau-drivers:amd64 11.2.0-1ubuntu
libsensors4:i386 [removed]

(N.B. I downloaded the 2.4.83-1 versions of the libdrm packages manually
from archive.ubuntu.com since the older version 2.4.67-1 in the xenial
repository created many dependency problems. These are therefore not
precisely the same package version as they were before the upgrade that
caused the symptoms.)

Title:
  Recent libgl-mesa graphics update prevents drop down list menu
  appearing in apps like firefox three line/bar menu icon

Status in mesa package in Ubuntu:
  Confirmed

Bug description:
  PROBLEM

  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.

  
  BACKGROUND

  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.
