Grid plugin places windows incorrectly when dragged to right edge

Bug Description

Dragging a window to the right edge of the screen causes it to overlap the adjacent workspace by a few (between one and maybe four) pixels. This causes the unity launcher to disappear on the adjacent workspace, and clicking the app's icon in launcher to behave oddly (as the window is technically on the workspace, though not meaningfully so).

steps to reproduce:

- Pick a window on either of the left workspaces, ensure no windows are displayed on the other spaces
- Drag the window to the right edge, and snap it there (gold rectangle)
- Switch one workspace to the right

Expected behavior: Launcher is still visible, snapped window is not visible

Observed behavior: Launcher is hidden, a few pixels of the right edge of the snapped window are visible on the left edge of the workspace.

I am currently experiencing this bug in 12.04 (alpha 1, most recent updates were earlier today) in Unity 3D.

Left edge snap and top edge snap appear to work as expected.

This happens to me too, and has for a couple of Ubuntu releases. Also, the overlapping window stays focused. Today I switched to the workspace to the right, pressed Alt-F4, and accidentally killed a long running MATLAB process in the original (left) workspace.

Running an up-to-date 12.04
