I say "artifacts" because that's kinda what they look like, but not normal ones. It's not incorrect pixels, it's rectangular blocks, anywhere from 2x2 to 2x12 pixels in size. My graphics card doesn't seem to be overheating, as it stays under 50C (aftermarket cooling = ) throughout playing LFS.
And it either shows up at the beginning, or never at all. It's really kind of confusing. I also can't seem to figure out any pattern, as it doesn't show up that often (maybe 5-10% of the time?).
EDIT: look at the bottom of the screenshot. It only happens down there. Sometimes it's about as "tall" as that, sometimes it's about 2-2.5X taller, going up to the middle of the gloves or so.
EDIT2: Eh, also, it seems to happen a fair amount of the time when I Shift+F4 after the game is behind a window (like this webpage) for a few minutes. But if I then alt-tab from in the game, back to this webpage, then click on Live for Speed in the Start bar, it'll be gone.
