The following bug sits in the current OpenGL driver for Intel's integrated chips, coming with Fedora Core 6:
Tungsten Graphics / Mesa DRI Intel (R) 865G 20050225, 1.3 Mesa 6.5.1
Needless to say, the following works with all other drivers and operating systems I tested:
If I set glRasterPos3i to the bottom left corner of my visual, e.g. glRasterPos3i(-512,-384,0) if my visual has a resolution of 1024x768, the subsequent call to glDrawPixels doesn't do anything at all.
Workaround: set glRasterPos3i one line higher, e.g. glRasterPos3i(-512,-383,0)
