Huge patch with almost no stars

It's rendering issue - thanks for report.

Could you try to reproduce this outside of virtual box? I don't see an obvious reason for that right now. Maybe a mmap problem as the star catalog is mmapped..

Here is a video of this issue (in Ogg Vorbis format), showing how this starless patch moves as time is being fast forwarded.

It's Stellarium 0.13.0 build 6866 on Linux64 (Xubuntu 14.04 64bit) running inside VirtualBox 4.3.12.

Can you check this issue on "hardware"?

I could reproduce this bug on a native system (without VirtualBox being involved) as well. New video is attached.

It's the same Stellarium build and a fresh profile, again on Xubuntu 14.04 64bit.

Fabien, I can reproduce it on hardware. I guess this issue has been introduced after refactoring the feature of rendering the stars.

Apparently the bug comes from the commit r6320.

In ZoneArray.cpp, line 513, reintroducing:

    if (!cap.contains(vf))

fixes the issue.

Thanks for work, Guillaume, but this patch doesn't fix the issue for me. :(

Guillaume, seems you are fixed this issue with work on spheric mirror distortion. O_o

Should this be fixed in builds as of commit 7069? Still seeing the bug there.

Are you tried 0.13.0.92?

Are there Linux builds of 0.13.0.92? I only find Windows + OS X builds at https://launchpad.net/stellarium/+download

I installed build 7069 downloaded at https://code.launchpad.net/~stellarium/+archive/ubuntu/daily

Is 0.13.0.92 newer than build 7069? To me, build 7069 looked newer.

0.13.0.92 is 7068. It's odd because I can't reproduce this issue now. I'll check it again tonight.

Could there be a problem left which is specific to Linux?

OK, I can reproduce it on Windows with old Intel GPU

Ouch... I can reproduce it on linux too but only for specific time of the day.

This spot moves around the Southern celestial pole roughly at about 50° S as you advance in time. See attached video.

I just pushed a change that should probably fix the issue. rev 7070. Let me know if you still have the same problem.

Awesome, now the problem is gone :).

Thank you very much for the fix!

It's the monolith from 2001 A Space Odyssey.

I too see the problem in 0.13.0 on my Win7 64-bit i7 with GTX 460 and 337.88 driver.
If anyone wishes, I'd be happy to try the fix, if a Windows build is available.
