The point was that the right column hasn't changed diameter, neither reduced or expanded. The left hand column, or rather the content area, has expanded for all users, more so if you have a wider than average screen.

I'd guess the text within the most played games module is too long and has caused the module to overflow outside it's normal width, causing the cut-off you see.
