Common Problems for the current version
If you are new to Stellarium: we were hosted at Launchpad until December of 2017 (https://launchpad.net/stellarium). There you can find notes about common problems found with slightly earlier versions of Stellarium. These include graphical problems with not-so-new computers or when you did not install current graphics card drivers.
Problems with older versions are described here: https://github.com/Stellarium/stellarium/wiki/FAQ/_edit#common-problems-with-older-versions
On some Linux systems with some NVidia GPUs the daylight sky appears pink. Using the proprietary binary driver from NVidia seems to solve this issue.
OpenSSL problems in the Logfile, missing HiPS Surveys, cannot download additional star catalogs (Windows)
Solved after #260; repeated #269, #270, #533
0.18 series: If you want to configure HiPS surveys and the solar system objects list is empty, the logfile may show errors around

2 solutions:
- You need to install OpenSSL libraries e.g. from https://slproweb.com/products/Win32OpenSSL.html or elsewhere. (This site is not related to Stellarium.) Install at least the 32bit Lite package of OpenSSL version 1.0.2, NOT 1.1.0. Then compile Stellarium yourself.
- Install a Beta package. Builds from 2018-08-26 and later have solved this by including the OpenSSL 1.0.2 library in the package.
Reported in #63, #66, #92, #93, #94, #95, #98. Solved after #63.
In fact, any lunar eclipse crashes version 0.17.0 because in the move to Github a texture was lost. Please use any more recent version, or find the latest beta version at http://stellarium.org to see the most recent changes regarding Lunar eclipses.
Yes it is true, this WAS a bug. Please do not report again.

Series 0.17 and 0.18 have a problem with the latest version of ANGLE on Windows, so that planets are not rendered correctly. Use the following workaround:
- Install an older version, e.g. Stellarium 0.15.2, into a different folder like C:\Program Files\Stellarium_0.15.2.
- From the Stellarium 0.15.2 directory (C:\Program Files\Stellarium_0.15.2 in the example above), copy libEGL.dll and libGLES2.dll and place them into the Stellarium program directory (default C:\Program Files\Stellarium; overwrite the DLLs which had been installed). Now planets show up. :-) You can also uninstall the older version now.
Version 0.18.3 and later do not have this problem.
We have changed the GUI to become more interactive. Unfortunately this introduced the default activation of "Lens#0".
The easiest solution for now: ADD A 1-SCALING BARLOW LENS in the Oculars GUI:
- Open the Lenses tab - Add a new lens: Name e.g. "None", scale factor 1.000 - Use the [+]/[-] buttons at the bottom of the GUI panel to put this lens on top of the list. (This makes the 1-lens the default.)
Stellarium currently does not account for aberration of light. This causes a slight error in positions which is usually negligible, except when it comes to the exact times of seasons' beginnings. For the time being, please use some other tool to find out the exact minutes.
Constellation lines and artwork are not internationally standardized. Stellarium has its own default version of the line art which is close, but not necessarily identical to that found in other popular sources. This is not an error. Some particular versions are available in the sky cultures settings.
Some operating systems, web browsers or malware protection systems claim that downloading or installing Stellarium may be dangerous because the publisher is unknown, or the installer has not been signed with some security certificate.
Apart from addictively stealing your time observing Stellarium's sky rendition, Stellarium is not dangerous and should not harm anything or anybody (but please read the GPL disclaimer about no guarantee or non-fitness for particular purpose etc.). The browser or install warning panel should offer some way to accept this warning and continue the download or installation if you are comfortable.
However, make sure to download Stellarium from stellarium.org, github.com, launchpad.net or sourceforge.net, and not some repackaged installation from freeware sites which may pack extra software or adware into their own installers or wrap our ready-made package into "safe downloader apps" (which usually add adware) or may change browser settings (change default browser, modify default search engine, ...) or other things you don't want and we cannot control.
And DO NOT PURCHASE STELLARIUM FROM EBAY OR AMAZON. Whoever sells the desktop version is taking your money without contributing a single line of code to this project.
On Windows this indicates your system may be running in "Mesa Mode". This may happen when hardware rendering is disabled because of missing drivers, or if you don't have compatible hardware-accelerated graphics at all. Your PC may be too old (from 2008 or older, or some netbook with Atom CPU from 2010?) If you have a 3D video card or at least a modern processor (CPU) with built-in GPU capabilities, make sure that your OpenGL drivers are installed and up to date.
You can download up-to-date drivers for:
- nVidia cards from site: http://www.nvidia.com/Download/index.aspx?lang=en
- ATI/AMD cards from site: http://support.amd.com/us/Pages/AMDSupportHub.aspx
- Intel cards from site: http://downloadcenter.intel.com/default.aspx?iid=gg_support-EN_01+home_downloadctr
This is a known long-time defect for the default OpenGL mode on Windows when you have Mouse Trails enabled or another reason to use a "software cursor", like f.lux screen color temperature modifier.
Workaround (1) Use ANGLE mode when you need mouse trails or f.lux.
Workaround (2) Make sure to switch off mouse trails to avoid this problem.
Update OpenGL drivers or run ANGLE mode with DirectX v9. To run Stellarium in ANGLE mode, press START, go into the Stellarium program folder, and start "Stellarium (ANGLE mode)"
Translations in Stellarium are a community effort, so it is possible that a local translator started the project, but never finished it, or didn't find help with some specific words.

If you are lucky enough to have a High DPI screen (4k or similar), you may find the GUI fonts are too small. We received an anonymous hint with a solution (untested by us) that may work at least on Windows:

You can reduce text label size requirements a bit by reducing [gui]/base_font_size in config.ini. But a 600 pixel screen is really very narrow, we need some space for the many options. More people complained about the tiny GUI on their 4k screens...
Some other software titles reject to start with less than 768 lines of screen space. There may be a screen driver setting that allows setting 768 lines which are then squeezed back to the 600 physical display lines. This enables you to use those programs, but of course this distorts the view vertically. To compensate the distortion in Stellarium, you can use a startup.ssc script in your scripts folder:
// Startup.ssc for netbook screen setup. // Author: Georg Zotti // This is usable on a netbook with physical 1024x600 screen with a display driver set to // 1024x768 resolution. GUI panels may be better accessible with such setting. // The distortion caused by this setting will be compensated by this script. core.setViewportStretch(600/768);
Note that this only (un-)distorts the projected sky, not any GUI panels. These will still require their pixel sizes, which is often a bit more than 600 lines, but the program thinks it is running in 768 lines and the panels should now fit. Legibility of some labels may suffer a bit, though.
On Windows and with some older models of NVidia GeForce (reported for 580M, 770), the color settings dialog in the gridline panel and ArchaeoLines plugin, and the file dialog for changing screenshot directory may hide behind the full-screen window when Stellarium is running in Fullscreen and OpenGL mode. The color dialog works in ANGLE mode. On a GeForce GTX 960M we see no problem.
A similar issue has been reported for an Intel HD4600 system with driver Build 10.18.10.3412. On another Intel HD4600 system with driver Build 20.19.15.4835, we cannot reproduce this issue.
We interpret this as NVidia (or Intel, resp.) driver issue. If you are affected, run Stellarium in ANGLE mode or leave fullscreen mode before changing colors or directory. Pressing ESC should close the hidden system dialog, or press Alt-Tab to switch windows.
