Spring RTS Engine

I have had this bug since the .77 releases, all the way up to the latest release.
Whenever i scroll the screen around, or move the camera, I get these black flashes on the terrain where it is not completeley smooth. Ive tried playing around with every available spring setting and with nhancer, but nothing helped.

Here is the video showing what this looks like (x264) its zipped cause forum wont let me upload avi

Did you try a different water renderer? If a different water renderer works, the black flickering with bumpwater is a known (and complicated to fix I heard) bug.

Thanks a bunch, that seemed to be the bug.
