Comment 8 for bug 1025706

Hello,

> XenClient Enterprise ships with Cairo-dock, and uses non-square icons as thumbnails of VM screens. If the system has a 16:9 display, the dock will contain a 16:9 icon for each running guest.

Yes but it's not a problem because the icon is wider than high :)
This is how it looks like with Gimp when editing a screenshot (16:10)

(Note that it's also possible to use icons sizes that are wider than high and you can also specify a custom size for each launcher)
