Using: Ubuntu Mate 16.04, updated to current
Google Chrome v50.0.2661.75 (64-bit) (current)
NVIDIA driver 340.96 (from the repositories)
Compiz
I noticed that, when one unticks “Use system title bar and borders”, Chrome allows you to save ~24 pixels at the top of your screen by not displaying the customary title bar, but nothing happens when one left-clicks or right-clicks the desktop. No context menu on a right click. No activation of desktop icons on a left click. (The Mate panels work fine; it just affects the desktop.)
When one “turns back on” the system title bar and borders, the ability to left-click and right-click on the desktop comes back.
Has anyone else noticed this, and found a solution?
