User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36

Steps to reproduce:

In Firefox developer edition (same error in Firefox normal edition) I experience after some time that the three buttons in the top right corner of the browser window; minimize, maximize and close are invisible. See attached image.
I use Windows 10 Preview. I don't see this problem with other browsers (Chrome and IE) or Windows File Explorer.


Actual results:

Three top-right window buttons invisible and not useable (I can't even click the area of the button and get a response).


Expected results:

The given functions not working

Does this happen after Windows changes theme? (i.e. Windows Classic -> Windows Aero)
This something Windows is likely to do if it enters/leaves a power saving mode. It can also happen if you have laptop witch switchable graphics (which probably toggles the power saving mode).

So I wonder if this is a duplicate of bug 656891.
