Hair Rendering Bug/Dots Appearing in Hair

In certain scenes and lighting hair will get these dots all over it that will appear for a second then disappear. The dots will keep re appearing for the entirety of a scene sometimes. Seems like a rendering issue, and playing around in the settings doesn't seem to fix it. Have all settings on high and PC more than capable of running game. Have noticed it mostly in sunny scenes, and scenes with certain backlighting. 

Have seen this issue in a few posts. Hopefully there can be a fix as its rather annoying. If anybody has had a similar problem and managed to find a solution help would be appreciated!
