Laggy Graphics After Upgrade to Ubuntu 13.10
- by John bracciano
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).
