I am on Ubuntu 11.04 and the text in all the applications often looks with visual artifacts. I have installed xserver-xorg-video-intel.
Attached a image so you can appreciate.
lshw -c video output:
*-display description: VGA compatible controller product: 82945G/GZ Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 02 width: 32 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:16 memory:dfe00000-dfe7ffff ioport:8800(size=8) memory:e0000000-efffffff memory:dfe80000-dfebffff
In the text selected in green you can see the 'Online', 'File' and 'hassle' words cut.
