Unreadable fonts (Stellarium 0.10.3/0.10.4)

Windows users can download a test build from here: https://launchpad.net/stellarium/+download

Try both shortcuts in Stellarium's Start menu folder - "Stellarium" and "Stellarium (no OpenGL)". If only the second one works OK, you can copy it to the desktop and replace the default desktop shortcut.

If you still have problems, please report and ask questions through the usual channels (Stellarium's bug tracker, Stellarium's forums).

Stars Render As Squares

Problem Description

Dialog windows are rendered incorrectly (ATI Radeon video cards)

Problem Description

Some of Stellarium's dialog windows (i.e. the ones accessible through the left menu) are rendered incorrectly, making them unreadable. (The effect has been described as "out of phase"; see the links below for screenshots.) This issue seems to be limited to computers that use ATI graphics cards. It looks like this:

Solution

Update your graphics card driver to the most recent version possible. Several users have reported that this fixed the problem, although it seems that not all cards con be fixed in this way.

Drivers can be downloaded from ATI's official website, but it seems that ATI does not offer support and drivers for all Mobility Radeon models - users are supposed to get drivers from their laptop/notebook's manufacturer.

If you have this problem, please add your details to this list so the development team can get a picture of what is going on:

Quick Alternative Fix

If your graphics card does not have the adequate drivers to solve this problem, there is an easy quick fix (which must be done every time you open a new dialog box) that allows you to see the dialog boxes correctly.

Slowly resize the width of the dialog window (by dragging its border with the mouse) while carefully observing the distortion in the dialog box. The distortion will gradually get better until, at a given exact width, the dialog box displays correctly. (see talk page for more info).

Fix in 0.10.3

For users where version 0.10.1 worked OK, but 0.10.2 did not, the next release should bring some relief. The default graphics back end was the QT "native" mode in 0.10.1. This was changed to "raster" for 0.10.2 to fix a lot of OSX problems and because it improved GUI rendering performance a lot. Sadly this seems to have triggered the glitch for many radeon users.

In version 0.10.3 the default is "native" rendering on PCs, and "raster" on OSX. There will be a command line option to select "raster" or "opengl" on all platforms which may mean performance increases, but the default should be safer.

Problem Description

Font rendering messed up.

Solution

Add the following line to your config.ini in the [main] - Section:

use_qpaintenginegl2 = false

This worked for me and everything is now perfectly readable (Win7 x64 with ATI X1800XT) !

Stellarium 0.10.4 - I have the font rendering problem on an Acer Aspire 5515 (Windows 7) with ATI Radeon X1200 Series driver (version 8.593.100.0, dated 09/29/2009).

Stellarium 0.10.5 - I have the font rendering problem on an Acer Aspire 5732z (Windows XP SP3) with Mobile Intel 4 Chipset (GMA4500 M, version 6.14.10.5284, dated 07/20/2010).

Stellarium 0.11.0 - I had the font rendering problem (missing usual vowels a,e ..., but strangely not ê,à ... !) on a portable Asus X50R (Windows Vista Family Premium, French) with ATI XPRESS 1100. The change in config.ini (located in not easy to find and hidden (I used Total Commander, admin mode to edit it) c:\users\MyName\AppData\Roaming\Stellarium solved the problem. Dated 08/14/2011). Change was as posted : Add the following line to your config.ini in the [main] - Section: use_qpaintenginegl2 = false

Now in French : Stellarium 0.11.0 - Il y avait un problème de caractères manquants (absence des voyelles usuelles a,e ..., mais bizaremment pas des ê,à, etc. !) sur un portable Asus X50R (Windows Vista Family Premium) avec carte ATI XPRESS 1100. Le changement dans config.ini (situé / caché à cet endroit (J'ai utilisé Total Commander en mode Administrateur pour l'accéder et l'éditer) c:\users\MyName\AppData\Roaming\Stellarium a résolu le problème. Date 08/14/2011). Changement à faire comme posté : Ajouter la ligne suivante dans config.ini , section [main] : use_qpaintenginegl2 = false et sauvegarder !
