Bug description: Since xf86-video-intel 2.99.911 i noticed some pixels burned in my monitor, in the top right corner, all icons(volume icon, network icon and so on) on bar are burned into my monitor, after a few hours of usage. Of course, burns arent permanent and keeping full screen white picture for a day heals my monitor almost completely. I use mostly windows 7, but havent noticed anything like that happening in windows, so i guess it isnt old or broken hardware, my lenovo laptop is only about 2,5 years old.
