I have noticed an effect best described as dancining pixels on my Lenovo IdeaPad Y560p. I have tried different operating systems [Win7, XP, Ubuntu, and Fedora], all with correct drivers installed [Ones off support.lenovo.com for Windows, Catalyst drivers from ATI for Linux] and still have the same issues after doing all updates/etc...
What could be causing the dancing pixels?
A new BIOS, version 21 has been released for the IdeaPad Y460p and Y560p systems to address the dancing pixel symptoms. Please install this BIOS and ensure drivers and Catalyst control center are to the latest levels provided on the Lenovo support site.
