Description Andreas Kloeckner 2007-12-18 07:26:17 UTC

Surfaces that used to (and are supposed to) be double-sided in scientific visualizations turn out black on one side (the "top")

Steps to reproduce:
1. Download a Paraview binary (or compile from source, if you like pain) -- see http://paraview.org/New/download.html
2. Start it
3. Click Sources > Plane
4. Hit "Apply" on the left
5. Rotate the plane with your mouse
6. Observe that one side of it is black (and unlit)

This is on an i915 in a Thinkpad R52 with X.org 1.4, Mesa 7.0.2-2 and intel 2.2.0-1 (from Debian).

Comment 3 Andreas Kloeckner 2007-12-19 07:26:48 UTC

Debian's 7.0.1-2 seems fine.

gordon, are we able to reproduce this and even bisect?

Comment 6 Gordon Jin 2008-06-29 18:41:08 UTC

Haihao, do you have any idea, or is this dup with others?

Comment 7 haihao 2008-06-30 00:48:11 UTC

Hi, gordon
   Does it works fine with mesa7.0.1? If it works, could you do a bisect ?

Comment 8 Gordon Jin 2008-07-01 20:37:42 UTC

Haien, can you try this with the latest stable driver first?

Comment 9 Andreas Kloeckner 2008-07-02 20:32:59 UTC

Works ok now, using 

- xserver-xorg-video-intel 2.3.2-1
- libgl1-mesa-dri 7.0.3-4

(all from Debian)
