    new cairo (1.12.10-1ubuntu1) & icon issues

    Can show up in both unity & gnome-shell though much more common here in Unity.
    Fairly easy to cause, (at least here), took only a few min. on a new current image install.
    Usually comes from using spread multiple times in a session on un-maxed nautilus windows with a key binding, by default super+w will pull all from current ws.

    Can be fairly minor or quite extensive, gets worse if using any custom colors, icons ect, or enabling picking from a window group instead of all.
    Attached to top of bug report is a vid showing middle of the road nonsense, attached below is 2 screens from new install, 2 nautilus home folders with a few borked icons in upper window

    The cairo drawing issues are very often due to graphics drivers incompatibility with cairo rules. I remember much more severe issues a while back with nvidia-current driver.

    Are you using nvidia proprietary dirvers?
    Which graphics card model you have?

    This is being seen on a 8400m with nouveau, may try nvidia drivers later to see. (being a aged somewhat crappy laptop adapter it actually works a bit better with nouveau than nvidia drivers unless I force nvidia to always use max perf which is default on nouveau.

    The screens & vid are relatively minor, on an install with a modded theme & the 're-enabling' of window picker for window group from all workspaces it gets much worse.

    (- I've a new laptop with much better hardware, (nvidia GTX660m) but haven't yet decided how to address the current partitioning. From a multimedia standpoint have no issue with win7 & optimus ect. so don't want to remove it yet or ever.

    If it doesn't go away on this laptop will just use the previous cairo for 13.04 unless I find the cause but the upgrade contained a boatload of commits so that may not happen.

    Edit: seemingly fixed with new upstream cairo 1.12.12
