Weird black squares on battlefield

[PunchDrunk]

Im getting this graphical glitch where black squares are showing up on the battlefield. I have my graphical settings on very high. Has anybody else experienced the same thing?

Note with patch 5

Known Issues
Changing the game's Texture Quality option during a campaign or a battle may cause the terrain to appear black. This can be avoided by changing
this option with the Game Settings in the main menu, and will usually stop happening after starting the next battle or re-loading your campaign. This will be hotfixed in the near future.

Ps: got the same problem
