Hey,
Thank you for sharing the information and screenshots on the matter.
We were not able to reproduce the terrain artifacts that you observed, and cannot confirm whether they were caused by the changes from the latest patch. To investigate the matter further, would it be possible to provide us with some additional information, such as:
Does the problem reproduce for every campaign you enter?
Are the artifacts present all over the map, or just in specific areas?
Could you please provide us with a DXdiag file? (Here are steps on how to obtain it)
Finally, I checked with the development team, and reinstallation of the game was suggested as a potential fix.
