Bug Description

Binary package hint: compiz

I have two windows aligned side by side on workspace "3".
If I am on workspace "1" and try to switch to one of these windows by clicking on the launcher icon the window jumps partly on workspace "1", instead of switching to workspace "3".

I have a video attached that demonstrates the problem very well I think.

I can also confirm this. I think it's only started happening recently (post final release) but I'm not 100% on that.

Steps to duplicate, starting with a clean desktop:

1. Open a window on workspace top-left
2. Switch to workspace top-right
3. Open a window and move it to bottom-right corner so it snaps
4. Switch between the two windows using launcher icons

The problem only happens for me if in step 3, the window is snapped to the edge of the screen and not maximised. It does not happen if the window is just very close to the edge of the workspace.

It also happens if Super-W is used to show all windows and the window is focused. The key seems to be focusing to a window on another desktop where that window is snapped right.

There is a slight difference in behaviour if the launcher is set to hide in some way or set to never hide. In the case of never hide, the window that is snapped right moves when switched to so that it overlaps another workspace. In the case of hide, the window does not seem to move but switching stops working.

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.
