Steps to reproduce the problem:
1. Start Canary as usual in Windows 10 (not in safe mode or anything)
2. Black box (if not in fullscreen) or screen (if fullscreen) comes up instead of browser
3. 

What is the expected behavior?
Instead of the usual chrome window, the browser is just a black screen.

What went wrong?
Instead of the usual chrome window, the browser is just a black screen/box (becomes a screen if it's made fullscreen). The buttons are in their usual places (X button and three vertical dots etc), but the issue is that i can't see what I'm doing.   I gave it about 10 minutes before eventually realizing it's just going to stay like that 

Did this work before? N/A 

Chrome version: 65.0.3293.0  Channel: canary
OS Version: Windows 10
Flash Version: Shockwave Flash 28.0 r0

I'm running Windows 10 and I switched the browser to compatibility with Windows 7.  This seems to avert the problem for now. 

I have the stable version of Chrome too and I don't have the issue on that version
