Original report by Nick Fedoseev: https://bugs.launchpad.net/stellarium/+bug/1425630

There are some places on the sky where wrong clipping occurs. It depends on

  • FOV, must be enough small;
  • atmosphere turned on;
  • sky position and/or time;
  • object type: grid and stars are clipped, while images are not.

Attached image may help to reproduce the bug with exact position, FOV and time. Site coordinates are 50N, 30E (near Kiev).
It shows the same place with atmosphere switch off/on.

(version 0.13.3)

The situation around wrong clipping on small FOV in version 1.0 happened worse than before, because wrong clipping may be see now for stars near bright objects, like planets.
