Package: libgl1-mesa-dri
Version: 6.5.1-0.5
Severity: normal
The usage of glPointSize() in an OpenGL program does change the size of
points which are drawn by a following GL_POINTS directive/block.
I'm using a radeon9700 card. DRI is enabled.
Screenshot of how it is supposed to work (winXp + mingw):

What OpenGL tells me about points here (see code):
point sizes (before drawing point):
min: 1.000000, max: 64.000000, incr: 0.125000, actual: 1.000000
point sizes (after drawing point):
min: 1.000000, max: 64.000000, incr: 0.125000, actual: 8.000000
Screenshot of how it actually works on my system:

What OpenGL tells me about points here (see code):
point sizes (before drawing point):
min: 1.000000, max: 10922.000000, incr: 0.100000, actual: 1.000000
point sizes (after drawing point):
min: 1.000000, max: 10922.000000, incr: 0.100000, actual: 8.000000

Because of this, it may be a driver issue, but I'm not sure and do not
know which package would be responsible then.
(xorg-ati driver, mesa-dri or ?)
