Does this work on Win 10 where the frame color is always white?  Seems like the
incognito icon will be invisible there if it's also white.

The mocks Sebastien provided show a black frame for win 10 OTR (although yea,
it's not implemented yet). Maybe you know something I don't wrt whether a black
frame for OTR makes sense on win10?

[Peter Kasting, 2015/11/17 21:48:31]

It's currently not technically possible to implement a black frame on Win 10.

We're hoping this will change down the road, but for now, assume the window
frame on Win 10 is always white, even in incognito.
