This is commonly referred to as a "tear" (as in "rip", not what comes
from the ducts in your eyes when you first see it on the $1000+
display you just bought.)

For what it's worth, I get something similar at 1080p or 1080i on my
Sony TV using HDMI. I am using OpenGL vsync, so the tear doesn't
move; it's always in the exact same location, and of consistent
shape. Unfortunately, I don't have another display device I can use
to see if it's the TV or the PC that's at fault.
