Lighting Bug - Shadows appearing

This has been existence since new lighting system was put in place; wanted to report it. Where shadows are suppose to be; there are black areas. When you start to move or look at them long enough depending on your distance from them; they will pop the correct shadow. I have included some pictures showing the issue and before and after photos. I know of 5 people personally that are having this issue and have different system specs, from amd to intel, to nvidia to ati, to windows vista to windows 8. its very universal.
