I downgraded unity's packages to the previous version (7.2.1+14.04.20140513-0ubuntu2) and with that version I'm no longer able to reproduce the problem.
The changelog of the current version (7.2.2+14.04.20140714-0ubuntu1) includes lots of screensaver changes, including changes related to the clipboard. Clearly, some of those changes don't interact well, at least with Chrome 35 and above, I haven't been able to reproduce with any other programs. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

However, occasionally I am unable to enter my password since the password box is not given focus. Clicking with the mouse in the password box also doesn't help. I've found that clicking the settings cog (top right) twice allows me to regain control of the focus and enter my password. Aside from the inability to enter my password in the password box, it seems that simply typing my password (or in fact any text) results in those keystrokes being passed to the full-screen window *behind* the greeter. This should not be possible and is a security issue: imagine if my full-screen console was connected to a remote shared session, or was running an irc client, etc.).
