The Problem - Morphological Anti-Aliasing (MLAA) from AMD Drivers
The culprit is called Morphological Anti-Aliasing, a feature introduced by AMD in its drivers for more recent video cards (AMD Radeon HD 5000 and 6000 series). This technology tries to improve the quality of images by applying full-scene anti-aliasing as a post-processing effect to all applications using graphical rendering functions included in the DirectX programming interface, used by default in Windows operating systems. Apparently, this technology doesn’t work that well and can cause issues with the quality of the images being displayed. Applications that use hardware acceleration to generate content and text are likely to have issues with this feature. Very common examples include Internet browsers with hardware acceleration enabled (Firefox versions 4 and above, Internet Explorer 9, Chrome 10 and above) and the applications included in the Windows Live Essentials suite.
The Fix - Disable Morphological Anti-Aliasing (MLAA) from the Control Center
First, right-click on your desktop and select "AMD VISION Engine Control Center".
In the "AMD VISION Engine Control Center" window, go to Gaming -> 3D Application Settings". In the Anti-Aliasing section, uncheck "Morphological filtering" and click Apply.
Save any work you might be doing, close your open applications and restart your computer. Then, open the application where you had issues and check if the problem is fixed.
The text should be crystal clear again, as seen in the screenshot below.
