Recently I encountered this bug, the first time I did not even notice it, but then I began to observe it more and more often. A couple of days ago I decided to find out in more detail how it works, what is needed for it, and so on. My guess is that it only works with fine textures, such as a Metal Plate or a tower at a military base on a PEI map. I also found out that it works at a distance of about 15 meters from the texture itself. This bug can only be seen on the video, but since it cannot be uploaded here, it will be on the links below:
In the first video you have to look at the tower, and in the second just at the plates, most of all it was noticeable at the end of the video on the right plate.
You only need to watch in 720p or more quality and with good vision.
If you can, it’s best to download the video and zoom in in the editing software so that you can see it better.
