Bug description:
  I was using Google Maps and Chromium froze up and crashed.  After
  this, rendering of the new Google Maps page causes jagged lines to
  appear in the browser page display section, until I reboot the
  computer.  Killing and relaunching Chromium doesn't fix the problem.
  The jagged lines still appear after computer reboot if I visit Google
  Maps again, and again won't disappear until I restart the computer.
