Chrome Version: 60.0.3112.26 (Official build) beta ()32-bit
Chrome OS Version: 9592.15.0 beta-channel nyan_big
Chrome OS Platform: Acer CB5-311-T1UU
Firmware version: Google_Nyan_Big.5771.63.0
Network info: Wifi OnHub

Please specify Cr-* of the system to which this bug/feature applies (add
the label below).

Steps To Reproduce:
(1) Start the Chromebook
(2) On the login screen, observe the flickering, the password input field acting (caret jumping around, input not being displayed)
(3) Once logged in (blindly typing in input fields still works), observe the undrawn patches on the desktop, or in any window
(4) Move the mouse around, it causes a lot of flickering with drawing artifacts happening everywhere on the screen
(5) Try clicking elements in the UI, it becomes unresponsive sometimes

Expected Result:
No drawing artifacts and flickering, ability to type text and seeing that text, ability to click windows and tabs

Actual Result:
See description in steps to reproduce

How frequently does this problem reproduce? (Always, sometimes, hard to
reproduce?)
Always

What is the impact to the user, and is there a workaround? If so, what is
it?
There is no workaround, the laptop became unusable as soon as it got the update. I had to submit this bug report from another computer.

Please provide any additional information below. Attach a screen shot or
log if possible.
The Acer CB15 that has the issue is in dev mode.
