Flickering shadows on grass

Unity Engine

Example video:

Hey guys, I just downloaded Unity 5.3, created a terrain object and placed some standard asset details on it - I get flickering shadows everywhere. I’ve googled this and tried the most common suggestions such as changing shadow distance etc. which makes no difference. An interesting point is that this was not an issue in the previous version of Unity I had (5.1 I believe). This issue occurred with a fresh project and default settings on everything and stays the same after many setting changes.

Anyone got any ideas?

Update: doubling the terrain detail resolution (to 2048 from 1024) and placing maximum density grass means that shadows on grass remain constant and do not flicker between grass and ground shadows within the patch itself, but the edge of the grass patch will continue to flicker.

Final Update: Issue appears to have been some issue when updating Unity. Trashed all Unity preferences from windows user folder and the issue appears to be resolved.
