font rendering still wrong

[Attila Vegh]

Planet and star names are not readeable after startup.
By using NoOpengl2 version , some labels become readeable, but others still not.
Old problem continuing from last year versions.

Please check attachement.

eg.: Vega,Betelgeuse,Aldebaran,Formalhaut readeable with NoOpengl2, but Procyon, and Pollux are not.

If I increase the base_font_size in config.ini, the formerly not readeable names become readeable, and the others not readeable.

No problem with toolbar reading, nor with object information panel on the left.
Have got problem with star/planet labels and other labels on skymap.

The adding og the line "use_qpaintenginegl2 = false" to the main section of config.ini, has got the same result as NoOpengl2 has. Some labels become readeable.

If satellite view option is on, none of the satellite names are readeable.

Opengl Extensions Viewer 4.0 app. sais: all OpenGl version up to 2.1 has got 100% function support. All rendering tests run without problem.

Additional info:

  I found on Qt developer site, that in case of font corruption in windows they advice to switch on ClearType.

  I made it on my xp, and it makes the fonts more readeable. Not perfect, but definitely better.
  I tried it with the Opengl2 version as well, but there is no improvement.

  The words on the picture looks so funny, because I use a hungarian localized version.

   Please look: "Horizont" (means horizon) on green horizon line really better readeable.

  To be honest, with this feature switched on, My letters in this comment are not fully well showed as they were before.

  More system info: Display is: DELL E198wfp LCD - I think has got some part in the story.

[Attila Vegh (vegatti)]

And more additional info + a solution for windows :

  I tried the latest version of stellarium (0.11.2 ubuntu package) under Ubuntu linux.
  The hardware is the same as mentioned above.

  NO corrupted fonts under Linux.

  I thought two things: 1: Linux ATI driver should be better for old ATI cards as the windos one
                                            2: Independent opengl library should work better
                                            3: QT should be newer version as included in windows executeable (qt is 4.7 in My ubuntu now)

  Then I tried something which was planned earlyer, but never done: I installed omega display driver on windows for my 1950pro.

    And..full success. No rendering problem in stellarium, even when running the OpenGL2 shortcut.
                                     I would offer this trial for all ati card users.

              I attache a picture with the same screen content to be compareable with the older posts.
              Please zoom in to se the rendering qualiy.

regards - Attila

One question: what is "omega display driver"?

[Attila Vegh (vegatti)]

The omega driver is a thirdparty driver for ATI cards. ((( for windows )))

It seems still fully OpenGL2 compatible.

http://www.omegadrivers.net/index.php?option=com_content&view=article&id=59&Itemid=58

The purpose to do something like that is to provide tweaking capability, and to avoid fake results in synthetic benchmark tests.

To give some background, I was not happy to see, that the vendor of My 5 year old top card selected it, as not supported by the new official driver. It is using a "legacy" driver, which seems to be not so perfect.

Instead of visiting the local store for a new card, I have choosen an alternative way.

[Matthew Gates (matthew-porpoisehead)]

Thanks for the follow-up Atilla. We have so many problems which seem to be to bad drivers, so to know there is an alternative driver which works better is a relief!

Please try Stellarium 0.12.0

[Alexander Wolf (alexwolf)]

Please try Stellarium 0.12.1

[Alexander Wolf (alexwolf)]

For some peoples still has problems: http://sourceforge.net/p/stellarium/discussion/278769/thread/810a1e5c/

[Alexander Wolf (alexwolf)]

It's weird, but I can reproduce this issue only with the few specific versions of Qt. Seems it's trobles in Qt, not in Stellarium.

[gzotti (georg-zotti)]

The numerous bug reports about bad fonts were mostly driver related no-fix-possible-for-us issues. Driver updates or progress in hardware mostly solved this. Can we let this 2012 report (from the v0.11 series, run on a deprecated OS) expire or is this really still useful to keep?

[Attila Vegh (vegatti)]

Dear all! At last I have changed my computer, and the new card is not affected by this bug.

Do not work on the history.

Thanks.
