My held tools on servers and offline have these strange dotted lines that move across it when I turn my camera. After some looking it seems connected to my OpenGl and Anisotropic/Anti-Aliasing settings and have tweaked them to others suggestions with no effect or difference. Besides the clear lines, the edges on everything else dont seem a smooth either, i am not running optifine or any other mods. To be specific they seem to effect the pickaxe, hatchet, sword, spade and hoe made of any matierial, but the matierial does effect the colour of the lines

I cannot reproduce this bug as i don't know how it even started or even when as it has been something i have ignored until now.
