I have the same problem but it isn't consistent - sometimes the window animations work, and sometimes they don't
usually they don't work for new applications I launch, but after they've been open for a while and minimized/unminimized a few times the animations work again
I don't think the problem is in compiz because it works fine with other docks/panels
I can't diagnose what causes the animations to start working again - but it seems to happen when a new application is opened
