Jup, still there.

Comment by Meta [ 01/Nov/12 ]

I can confirm that z-fighting is still there

Comment by Kumasasa [ 01/Nov/12 ]

Not fixed in 1.4.3, the texture fighting is still there.
@Mods: How do we reopen a closed issue ? Shall we clone that ?

Moved it 2/256f forward.

I can confirm that problem. Running Mac OS X Mountain Lion

Comment by Jesper the End [ 24/Oct/12 ]

Ah, yes, now I see it. I had to open the image in a new tab.
I think it has something to do with anti-aliasing (or not anti-aliasing in this case).
I think your graphics card is the problem. (not sure though)

No, look at the screenshot, the map in the item frame (in the center of the screenshot) shows horizontal lines which flicker when moving the mouse.
Visible just under certain distances and viewing angles.
Z-fighting occurs when the two planes are on the same Z-axis, here the plane of the map item and the background of the item frame.

what? I don't get it.
Do you mean the vertical lines that always occur with maps?
