description |
Test code fails on 7.9~git20100924-0ubuntu2 version of mesa running on Ubuntu 10.10. I haven't tested on other systems yet, and am not sure, in which component the bug actually is. The bug didn't happen on 10.04 systems with intel gfx.
Expected result:
When running the test program on my nvidia system (with ubuntu 10.04), it draws same triangle (one vertex at left, one right and third at the top, all centered) in various (constant for all vertices) colors.
Actual result:
When running the same program on my Asus 1215N (running ubuntu 10.10) using the Intel chipset, however, the first triangle is rendered ok, but next one (and all after that) have one red vertex at top left, another red at bottom center, and white top right.
This code works the same on both if I either:
1)Don't draw to front buffer
2)don't glEnable(GL_LIGHTING)
If glEnable(GL_DEPTH_TEST) line is uncommented, only the top line of upside down triangle will be drawn.
While drawing to front buffer probably isn't too common, it can result in whole program becoming useless, when rendering stops working.
The code itself doesn't make much sense, as it's based on bugles exetrace of a lot bigger project, with functions that don't change the outcome removed.
