Regarding unity, you are getting the lowgfx profile which is a degraded experience.
Maybe your hardware isn't up to snuff or maybe the setting is erroneous. I'd edit that file (.config/compiz-1/compizconfig/config) to this & reboot and see what happens (- if you're still using unity..
Code:
[general_ubuntu]
profile = unity
plugin_list_autosort = true
After editing go
Code:
mv .cache .cache.bak && reboot
