Description Bernard Godard 2011-07-22 11:50:07 UTC
Description of problem:
Rendering incorrect of Celestia 1.6.0 with all render paths available. Hardware: Athlon 64x2, Nvidia Geforce 7600GT; software Fedora 15, 32 bits, nouveau/gallium driver.

Version-Release number of selected component (if applicable):
1.6.0

How reproducible:
always

Steps to Reproduce:
1. run Celestia on Fedora 15 with nouveau driver and NVIDIA 7600GT and try different rendering paths (ctrl + V)
  
Actual results: see captured desktop: 
- rendering path Basic: complete garbage 
- rendering path Multitexture :  complete garbage 
- rendering path OpenGL Vertex Program :  some garbage only when the Sun is in the field of view.
- rendering path OpenGL 2 :  some garbage only when the Sun is in the field of view.

ERROR MESSAGE APPEARS ON TERMINAL WHERE 


Expected results: correct rendering


Additional info:
Works fine with all render paths on Ubuntu 11.04 64 bits on same hardware with nouveau driver (Gallium 0.4 on NV4B).

Comment 1 Bernard Godard 2011-07-22 11:58:43 UTC

Following error message appears on terminal where Celestia is run:
nvfx_screen_get_param:94 -  Warning: unknown PIPE_CAP 29
same message appears when glxinfo is run.

This message does not appear in Ubuntu 64.

Additional note:
On ubuntu same version of Celestia: 1.6.0

Comment 4 Bernard Godard 2011-10-04 17:34:02 UTC
Now on Ubuntu 11.10 beta 2 64 bits with same hardware, I get the same rendering bug in Celestia. However the error message "nvfx_screen_get_param:94 -  Warning: unknown PIPE_CAP 29" does not appear in the console, so this seems to be unrelated.

Comment 5 Bernard Godard 2011-10-04 17:36:12 UTC
This seems to be a regression in the nouveau driver since the previous Ubuntu release didn't have this problem. I haven't tested on a more recent Fedora.

Comment 6 Bernard Godard 2011-12-26 17:06:11 UTC
Now on Fedora 16.

The error message in the console is not present anymore.
But there is still a rendering problem:

All stars are rendered with:
- a circle delimiting the star.
- a conic region starting at the center of the star and whose base is a small patch on the star surface. The rest of the star interior is black.

Comment 7 Fedora End Of Life 2012-08-07 18:39:00 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
