Ugly artifacts when drawing Unity elements with OSS and proprietary driver (AMD Radeon HD 3200)

[LostinSpacetime]

I can see artifacts on fonts, icons, buttons and practically everything drawn within Unity. I will provide screenshots to document the problem better. I installed the proprietary driver as well and I had exactly the same problem. Outside Unity everything is perfect.

Thank God I'm not alone with this one! :D I need the UI to look clean(or even pretty) since I'm installing Ubuntu on people's computers for living and use my laptop to show them what they'll get.
