There are two texture anomalies on the lenses of 3D scopes. Pictures have been attached that show the bugs in question.
One has to do with the edges of the lenses themselves, the other has to do with the illuminated portion of the crosshair. {F20230} {F20231} {F20232}
1.) Equip a weapon with the "RCO" scope affixed to it.
2.) Note the two texture anomalies, as demonstrated by the attached pictures.
The bottom most one is caused by Depth Of Field setting, the higher it is the blurrier it will be, it happens on all weapons...though I figure in terms of optics it shouldn't be there.
