This is what happens when I scroll a window (click for full-size versions): It can happen in any application, even in Chrome. My computer's specs: ASUS p8z77-v motherboard Intel Core-i7 3770k Intel HD Graphics 4000 integrated VGA Windows 8 Pro x64 I have tried to reinstall VGA drivers, tried to install an older driver from intel.com or asus.com, but no success with resolving the issue. Currently I am using driver version 2867. How can I fix this?
