I have a late 2011 Macbook Pro and Chrome running Version 33.0.1750.152
I also have a new HP something or other running Windows 7 and Chrome running version Version 33.0.1750.154 and it had the problem. I just updated to version 34.0.1847.116 m and that seems to have fixed the issue on the PC.
No update for the Mac yet though.
I don’t know what’s going on. Very weird. Here is a screenshot of what it looked like on my Mac.
