Funny enough, with my compiled svn version, there is a line down the middle, the right side the grass is black, the left is correct, and also the hole near the entrance is still there.
But using the linux x64 release version, there are only a few black spots, and the hole is closed in.
I tried setting the all the config files exactly the same, and copying across the svn psclient binary, it made no difference, so my guess is it's one of the included system libraries in libs/ in the release version, I will test more sometime.
