  STEPS:
  1. Install the latest image
  2. Open the browser
  3. Goto ubuntu.com
  4. Wait for the page to load
  5. Scroll the page

  EXPECT
  Smooth scrolling and rendering as seen on arale and krillin

  ACTUAL:
  Very slow render time on most site with a lot of content
  Scrolling is glitchy and seems to want to fresh render each page as it is 
scrolled

  This is most prominently seen on ubuntu.com but also ebay and amazon
  webapps.

  Webbrowser seems to display the issue the most although I beleive it
  is more likely to be the graphics stack somewhere, tvoss believe that
  perfservice will hopefully solve the issue.

2016-04-20 Thread David Barth 
@kgunn: no, we haven't produced that data, but I assume you guys have some
egl unit tests handy to get a confirmation.

I think we're making reasonable guesses here: Chris has shown that all apps
are affected, not just Oxide. And John indicates that the very same driver
binaries work on Android, so there aren't so many things between apps and
drivers. And definitely that is not an Oxide, nor a Blink bug.
