--- Comment #2 from Matias N. Goldberg <dark_sylinc at yahoo.com.ar> ---
This could be caused by the Ubuntu's Unity Compositor (Compiz).
You could try forcing VSync off in one of Compiz config/tweak tools.

It could also be caused by the tear free parameter. To test that try:
xrandr --output VIDEO --set TearFree off

where "VIDEO" is the name of your monitor output; you can find out by just
running "xrandr" and it will list all of your monitor outputs. For example mine
reads:
HDMI-A-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y
axis) 510mm x 290mm
   1920x1080     60.00*+  50.00    59.94  
   1920x1080i    60.00    50.00    59.94  
   1680x1050     59.88  
   1400x1050     59.95  
   1600x900      60.00  
   1280x1024     60.02  
   1440x900      59.90  
   1280x800      59.91  
   1152x864      75.00  
   1280x720      60.00    50.00    59.94  
   1024x768      60.00  
   800x600       60.32  
   720x576       50.00  
   720x480       60.00    59.94  
   640x480       60.00    59.94

Thus I should write:
xrandr --output HDMI-A-0 --set TearFree off
