Spacecraft disappear when moving in time and full magnetopause opacity

[C. Philippe Escoubet]

with magnetopause surface with full opacity when the spacecraft are out of magnetosphere, if we step with time, they disappear (see screen shot (Screen Shot 2015-12-01 at 16.59.19) and field lines appear, we have to move again the 3D view with the mouse for the spacecraft and part of orbit to appear again (Screen Shot 2015-12-01 at 17.00.44)

I have so far not managed to reproduce the bug (Mac OS, ovt_macos_3_0_build6_BETA_commitf77d00b_2015-11-20.dmg).

I can do that every time and it is quit annoying if you want to look at the spacecraft orbit with respect to a boundary. Here are my steps:

1. load a state file using Cluster ltof for 2016-06-04 02:00:00 for 2d 6h and 10 min step with magnetopause around 60% opacity
2. time of the s/c position is 2016-06-04 15:40. if I point to the image with the mouse and rotate slightly the magnetopause/orbit, then the spacecraft appears very clearly
3. I now move forward the time by one step with the mouse, to 15:50, and the spacecraft and segment of the orbit that should be outside of the magnetopause become darker (similar to being inside the magnetopause)
4. if I repeat 2 I get again the s/c bright again.
