Summary: [Big/Kevin] Getting corrupted image on external display for a second when switching between modes. (was: [Big] Getting corrupted image on external display for a second when switching between modes.)
Facing same issue on kevin_9202.4.0
It's not reproducible on sentry_9202.4.0/paine_9202.1.0. 
Labels: -Pri-2 M-56 Pri-1
The issue is reproducible in Chrome OS 9000.76.0, 56.0.2924.79 on Kevin. Tested on HoHo/Apple Type-C dongle. 

Also noticed that Kevin screen blinks 1+ second when connecting to external monitors.  
This is happening on all boards, it's not specific to type-C or kevin. It has been like this since pretty much forever...
Corrupted image is still seen when switching between mirror and extended mode in Chrome OS 9202.28.0, 57.0.2987.54 on Kevin.
