Having observed this for a while now, it seems to only affect windows that are snapped to the extreme right of the workspace grid, i.e. workspaces top-right and bottom-right in a 2x2 grid. Following on from the last paragraph of my comment above, I'm guessing that the space taken up by the launcher is not being taken into account in the coordinates of windows. When a window does overlap another workspace, it looks to be exactly the width of the launcher.
