What steps will reproduce the problem?

I have no idea how reproducible this problem is. I was using the pixelbook normally yesterday, closed the lid and let it sleep overnight, woke it up today by opening the lid and the screen would basically not redraw. The mouse pointer worked, pressing the Chrome button to display the Chrome menu would somewhat change the appearance of the bottom half of the screen where the menu should appear (but it didn't properly render the menu), and I could hear sound effects coming from apps like when I receive a message. If I closed the lid and then reopened it, the screen would update properly - once. I tried briefly pressing the power button long enough to return to the login screen (which rendered properly), then logged in again, and the desktop screen would not render properly.

Using Alt-Tab to switch windows would render a proper-looking task switcher, but when I switched to a different window its contents would not render properly.

I then hard rebooted by holding the power button longer, and when the machine rebooted I had a bunch of extra browser tabs presumably from clicking around in the dark.

I imagine this bug report won't be super useful beyond asserting "this bad thing happened in the Chrome OS display stack", but is there a key combination I should press or a tool I should run next time if the machine gets in this state again?
