I have seen that there are many issues it seems with Lion and screen artifacts.  I went through the threads and could not find this problem described.  When I boot up there are many times where there are artifacts at the login screen or prior to the login screen even showing.  Ran AHT test and it came back negative, but in the past these issues usually mean a hardware issue.  A screen shot of the log in is below.  Computer is all up to date on the software side of things, stock parts straight from Apple, no memory or hard drive changes.  Nothing to play with the OS at all to change appearence of anything.
