Hi Timo,
To test I removed the package holds, updated and upgraded to current
released packages, and then rebooted. At this point I confirmed the
issue in the original report.
Next I enabled the xenial-proposed repository, updated and then
installed the following two packages:
sudo apt install xserver-common/xenial-proposed xserver-xorg-core
/xenial-proposed
Then I rebooted. After reboot I confirmed that these proposed xenial
packages did indeed fix the issue. I was once again able to click on
the three line/bar icon in Firefox and see the drop down menu list
display. I also confirmed that there were no regressions in my testing
(no SDDM hang on login, and no screen tearing).
Following is the output you requested earlier.
$ apt-cache policy xserver-xorg-core
xserver-xorg-core:
Installed: 2:1.18.4-0ubuntu0.8

Thank you very much for fixing this problem and seeing it through to
xenial-proposed. If there is any more steps you need me to take to get this
into an official release package then please let me know.
Sincerely,
Curtis Gedak

Title:
Recent libgl-mesa graphics update prevents drop down list menu
appearing in apps like firefox three line/bar menu icon
Status in xorg-server package in Ubuntu:
Invalid
Status in xorg-server source package in Xenial:
Fix Committed
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.
