I recently found this bug, it happens when i'm near something that has a distortion effect, like the time wound on the throat of the world. and at those map borders found in soul cairn. also i found same lines around my hand when using fire spells.... http://i282.photobucket.com/albums/kk254/RGakaChris/ScreenShot2.jpg i've reinstalled skyrim, disable and enable all mods, tweaking skyrimprefs, and i still get those lines....disabled AA and AF, even trying low detail.. and it's annoying i use GTX 560TI, with a Q8400, and 4GBs of RAM...
