Stripey ground?

[Larkfall]

This is scary D:

I went onto flourite Plains, and instead of the normal green grass, it has turned to alternating stripes of lurid green and brown!

Highly worrying. D: I restarted the game, and it was still there. No-one else could see it.

It's never happened to me before, either. Help?

Try to reinstall the game

I`d go to options and switch the rendering subsystem, then restart the game. If no effect, try what Rimfrost said.
