Steps to reproduce the problem:
1. Open the "Developer Tools" on any page (F12 or Ctrl+Shift+I rightmouse + Inspect)
2. Open the "console drawer" (ESC)
3. Open the "Rendering" tab (left of the "Console" tab in the "console drawer")
4. Check the Layer Border checkbox

What is the expected behavior?
I expect to see the layer borders in a orange/olive colour and to see tiles in cyan. As is shown in attachment 2.png.

What went wrong?
Nothing changes on the page. As can be seen in attachment 1.png.

Did this work before? Yes not sure exactly probably chrome 58

Chrome version: 59.0.3071.109  Channel: n/a
OS Version: 
Flash Version: Shockwave Flash 26.0 r0

This occurs on chromium 59 on Ubuntu 16.04 and also on Window 10
