Description of problem:
After upgrading to xorg-x11-drv-intel-2.21.12-1.fc20.x86_64, I frequently notice small glyph corruptions (which though are very volatile, i.e. vanish as soon as the mouse hovers over them).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. I notice this particularly often using firefox and thunderbird (under kwin)
See attached screenshot.
GPU is a GMA 4500MHD
(Sorry for the not terribly detailed description, don't really have experience debugging graphics drivers. I'm happy to collect any additional information you may need.)
Looks like xorg-x11-drv-intel-2.21.14-1.fc20 fixed this.
