What steps will reproduce the problem?
(1) Run Chrome Remote Desktop.
(2) Connect to a host.

What is the expected result?

Expect that the session is stable.

What happens instead?

After a few seconds the screen goes blank (though I did briefly see it flicker what looked like the screen upside-down, as well).  The power light stays on, though.  Device has to be hard-reset by holding the power button.

This seems most likely to be a GPU issue, since CRD is just a Chrome App.
