screenshot of the bug
its actually hard to put it into words, updating to chrome 35 either through the ebuilds or via the official website results in an unuseable browser.
the address bar is missing, the first tab takes up most of the titlebar.
a picture sais a thousand words, so i guess its the best i can do.
I have never seen anything like that.
Feel free to report it upstream.
