[Windows] The thickness of the XYZV orbital lines varies with distance

[Lepestronik]

Describe the bug When moving away from an object with a sampled trajectory, the thickness of its orbit increases.

To Reproduce It can be reproduced on spacecraft with XYZV trajectories from version 1.7.0 (for example, "Cassini").

Expected behavior Thin orbital lines that do not change the thickness when the distance changes (like Keplerian orbits behave).

Screenshots

Desktop:

• OS: Windows 10 and 11.
• Frontend: native Win and Qt (Qt was not tested on Windows 11 because it could not be started there).
• Version: 1.7.0.

Additional context According to observations, it seems that as the thickness of the orbits increases, the load on the system increases.

Additional info: this effect disappears when anti-aliasing is disabled in the settings. On Linux both options look fine.

@Lepestronik are you sure that the issue is caused by the distance? On your screenshots orbits have different shapes and the first one is very close to a straight line tilted ~45 deg, so the second case requires much more pixels to render (try the same on a sheet of paper with cells).

So I believe this issue is about windows GL drivers rather than about Celestia.
