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.
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 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.

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:

To revert to the prior graphic drivers I tracked down the '.deb' 0ubuntu0~ 16.04.1' version.
packages for each of the above packages and downloaded the
'17.2.8-
For example:
https:/ /launchpad. net/ubuntu/ xenial/ amd64/libxatrac ker2/17. 2.8-0ubuntu0~ 16.04.1
I also discovered that some of these depended on 0_5.0-3~ 16.04.1 so I also downloaded the following files:
libllvm5.
libllvm5. 0_5.0-3~ 16.04.1_ amd64.deb 0_5.0-3~ 16.04.1_ i386.deb
libllvm5.
WORKAROUND (ROLLBACK TO PRIOR VERSION)
Install older versions with:

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.
