I think I have the same problem even though I'm not using KDE but just Ubuntu 12.04, xorg-edgers PPA, and a Unity desktop.
Since the 2:2.20.4+git20120820.027569bf-0ubuntu0sarvatt~precise build, my display has lots of distorted characters. For example, in a terminal window, my input is not even displayed or only parts of it. Then I scroll a bit, it suddenly appears. The behaviour is reproducable and is clearly fixed as soon as I downgrade to the 2:2.20.3+git20120816.94871944-0ubuntu0sarvatt~precise version. Please try to confirm: Download the 20120820 build and see if you have the problem, then try again with the 20120816 build and see if it is gone.
