Since recently downloading 1.5 Open Beta for DCS World on Steam, I have encountered visual bugs pertaining to multiple objects. Specifically, the problem fans to many objects within the game, the most problematic being the 9M14 Malyuktka model. The models affected appear to be hexagonal in shape (AIM-120B/C, 5V55R, Igla, etc.), or rectangular, as with the 9M14 shown in the picture below. Some of the objects affected also have missing fins, or other distinguishing features, like on the examples below, excluding the AIM-120C.
This problem has only been of an occurrence since the download of 1.5. Before the download of 1.5, 1.2.16 did not have the same problems as this build.
