Oh yeah, I know what you mean.
It´s kind of like that, but not quite as drastic.
The oscillation is at a very short wavelength, fairly rapid frequency.
My monitor is an acer flatscreen lcd.
It wasn´t doing this while using dapper just before upgrading to feisty,
so, I assume something in feisty changed something, rather than
any environmental factor.  No environmental factors have changed.
Good guess, though.
