I don't know if it's local for my machine, but after the update I've made to Chrome a few minutes ago, some pages are showing a large colored (single color) triangle with it's tip on the top left hand side of the page, resting on the top of the page, and with it's second base running ON TOP of the Chrome UI (the scrollbar) going about a 3rd of the way down to the page, flickering and rather annoying and making the use of Chrome in it's current version practically impossible.
This page shows the triangle for me: http://coderwall.com/p/fahbaq?i=2&p=1&q=&t=sublime-text-2
