Omnibox text jumps up and down while typing

[Marius Gedminas]

Steps to reproduce:
1. Type some text in the Chromium address bar

Expected behavior: text does not jump up and down

Actual behavior: text jumps up and down (see attached screencast).

Apologies for the large size of the screencast. I tried to unplug my external monitor to reduce the image size to 1366x768, but unfortunately GNOME Shell produced a 2646x1024 video anyway (most of it black), and the file size was larger in the end (3 megs instead of 1). And Kazam segfaulted when I tried to use it instead.

This is very similar to https://code.google.com/p/chromium/issues/detail?id=27103, except that bug was closed in 2009. Also, I didn't see this with Chromium 28 in raring.

If I go to chrome://settings/ and click 'Use Gtk+ theme', this problem goes away.

If I go to chrome://settings/ and click 'Use classic theme', this problem comes back.

If I install the Adwaita theme[1] to make Chromium fit in with the rest of my GNOME desktop, this problem comes back.

Status changed to 'Confirmed' because the bug affects multiple users.

This is fixed in trusty.

(Chromium in Trusty uses Aura, which doesn't have this problem.)
