There is a related thread …
… which however is explicitly not about “water” cracks … but it feels like this is falling in a similar category. I seems like in SU5 we have:
- Persistent non-healing cracks … in ground and water
- Shape shifting and healing cracks
It is still not clear if there is only one “bug” or if there are multiple causes. But what I think we could identify (especially with that crack at the coast of Wales) is that
- a) the elevation data seem to have cracks … or has data which triggers the engine to generate cracks
- b) those cracks are different in different LOD data sets
(b) is most likely the reason why some cracks are “healing” as the camera moves (if the crack is in a low res LOD data set) … and others do not heal.
Water might be slightly different as there is some active “flattening” and now with SU5 there is also additional active (wave) deformation. But @DJDonohoe took a screenshot of a interesting water crack, which suggests that the “active” deformation might not be the problem (as it feels consistent across a crack)
So far there seems to be no (useful) workaround.
