Ubuntu – Laggy Graphics After Upgrade to Ubuntu 13.10

13.10graphicsintel graphics

I noticed some issues concerning the graphics after I upgraded from Ubuntu 13.04 to 13.10. More specifically:

  • Dash tends to be more "laggy" than it used to be.
  • When I switch desktops you can clearly see the screen going frame by frame.
  • Menu bar is also "laggy". When I open GIMP, the menu bar is useless after a while – it takes seconds to refresh.

The problems seem to appear after some seconds of use. When I boot the system everything works fine, until some more graphics-intensive program starts (Firefox, GIMP, etc).

/usr/lib/nux/unity_support_test -p reports:

Thank you in advance for any answer!
