So I've had this slightly annoying problem when running gvim on Ubuntu. When I enforce full-screen mode I get white bars at the bottom and right of the screen. (I'm trying to emulate the Mac-vim full screen mode)
(I would have posted an image but I'm a new user and apparently can't do that.) Edit I think this screenshot using Xephyr shows what's happening at a reasonable screen shot size:

Note that the screenshot only shows a 'small' bar at the right. In reality, at 3328x1152 there is a significant 'panel-like' bar at both the bottom and the right of the screen
I've found very little on Google and nothing on stackoverflow about this, but that might be because I've got the wrong search params, but from what I understand it's to do with the window manager imposing restrictions on the window. If anyone knows a workaround for this I'd greatly appreciate it, I'm using the default Ubuntu window manager.
