What's the problem? How could that happen?
It's a glitch in safari... is your system updated? I've seen this problem with mine weeks ago. Seems to happen randomly. Nothing is wrong with your screen.
I think I've just installed the updates today.
It now happens to most of the pages I opened...
To me, looks like a big issue...I guess I need to go to store tomorrow.
If you have installed the graphics update and you are getting this problem, it's off to the Apple Store.
It may make you feel better to know that if it were actually the screen/hardware that it would not appear in the screenshot. This is a software thing and likely an easy fix.Do your update. However make note that sometimes text gets rendered funny on websites and there's no major problem, just happens.
Have you tried to go into international in system prefs and make sure that the language has not been changed?
