Menus and window movements take a while to respond, switching windows is slow, etc. This is a regression, it was not like this using Ubuntu 12.10, it just started on 13.04. Tried different desktops (Unity, GnomeFaillback, Lxde). They all have the same issue. Testing showed the issue is triggered by the TLP power management package. TLP was installed in an attempt to resolve issue of fan running constantly.
