When looking out over water, and void regions, there is a distinct line at one point in the view with a sometimes quite large specular highlight that should not be present. The sun or moon reflections spread out to that line.
It is noted that @Geenz is aware of this, that its been present in many 7.* viewers and that it could already be noted as an issue but low priority. Just reporting here as I had a clear snapshot of the issue. Attached.
Try testing looking West at various times of day and in shared environment as sun is higher in west sky at http://maps.secondlife.com/secondlife/Damiano/49/5/21
