fullscreen actual size wrong in Vine Viewer

i’m using Vine Viewer in fullscreen mode to view a remote desktop (on linux) which has the exact same resolution as the monitor connected to my mac. for some reason there are a couple of pixels wrong vertically it seems, so when i mouse to the bottom the whole screen moves. this doesn’t happen in other VNC viewers it seems.

What version of Mac OS X are you running?

oops, mavericks.
