[Canyon] Shadows High, Mountains looks strange

When I use the setting Shadows High I find that at some places the mountains looks very strange. That is particularily noticable in track C08. It can be seen at the first bridge over the water at the left side mountains. Some places of the surface are changing in an unnatural way when the car is moving. With shadows Minimum I have never seen that problem. Graphics card used is hd7750.

In this picture 1 and 2 shows shadows on the mountains that looks odd. When the car is moving even
only a little bit the shape of the shadows change. An example is in this picture.

The same phenomenon can be seen in circle 3. The shadows have very rude shape and are
moving all the time as the car moves.

In the last picture I have shown other edges. Also they are moving all the time the car
moves. Similar edges are also present in Stadium.

Is it looking like this for other players too or is something wrong with my system?

Do you mean this kind of sawtooth effect?
I also have noticed it, also in ShootMania when I was using too many lighting blocks in a larger "room",
but also at some wall parts.
So it is rather a generic ManiaPlanet lightmap calculation issue, nothing wrong with your system especially
It is a side effect of radiosity with insufficient detail or insufficient steps:

Perhaps you should try to have the lighmaps calculated in Ultra, and also use LightmapIndex activated in the advanced video settings.

Yes.

I couldn't set it to Ultra, but tried High and it made no difference. In fact I don't see any difference even between Very fast and High. Lightmap index didn't worked either.

I've seen that many times. I think it's always been like that and I always calculate on high.

As we are talking of shadows, please try the following: drive into a canyon, where you can see the hard shadow (not the lightmap shadow) of a opposite mountain or object fall on the mountain at other side.
Now slowly turn around... the shadow is moving... surprisingly
