-- Linux distribution:
   ChromeOS
-- Machine or mother board model:

Vedang, have you also tried nightly?  I saw this issue transiently on internal builds, but then it went away in subsequent images.
Comment 5 Vedang Patel 2015-10-23 18:08:28 UTC 
Just tested the latest drm-intel-nightly kernel. I can still see the corruption. Tested on WSB.

Patel - Sorry about this delay on getting back to you. Is this problem still valid with the latest ChromeOS ?
Comment 7 Vedang Patel 2017-03-08 17:35:39 UTC 
I don't think this is valid. You can close it.
