Public bug reported:
I am running Ubuntu 16.04.3 on a Macbook Pro using a dock with two
monitors. While docked, the internal display is not operational, instead
using only the two monitors. I have repeatedly encountered issues where
application windows that are active on the left display are not
selectable with the mouse. I can still use the Unity launcher bar and
the top menu bar but not any open windows. The windows on the right
monitor still work properly. If I drag applications from the right
display to the left display, that application also becomes unclickable
with the mouse. Windows that span across both display and clickable on
the right display, but not the left display. This behavior happens
occasionally (about once a week) with any running applications, and I
have not been able to cause the behavior repeatably. I can still use the
applications by using the Unity launcher to switch to the application,
then using keyboard commands. I would note that usually when this
happens, I have a Windows virtual machine running in Virtualbox. I'm not
sure if that is related or just a coincidence. At times, I can get the
OS operating correctly again by closing all open application windows.
Other times, it requires a complete reboot to restore operation to the
left side monitor.
