[wp-hackers] Extra columns in 3.8?

[Luke Bryan]

Greetings all,

I noticed wp3.8 dashboard home shows extra columns when the screen is
resized - although it's not obvious to the user what or why there is a box
to drag more widgets to.

Is there a hook or global to set to change it to two columns all the time?
I tried setting the global $screen_layout_columns = 2; but it doesn't work.
Do I need to wait for this bug to be fixed?
