Follow-up Comment #38, bug #44916 (project octave):
I've plotted the points you've indicated. See attached PNG file. (Screenshot
is better quality than the printed output.)
It looks as though the second data point is the one that is missing. In this
group of data, I've donated by ** the lines that seem incorrect:
LINE: 119.519989 82.727989 (0.000000 0.000000 1.000000)
LINE: 119.519989 82.727989 (0.000000 0.000000 1.000000) **
LINE: 208.800003 153.143997 (0.000000 0.000000 1.000000) **
LINE: 208.800003 153.143997 (0.000000 0.000000 1.000000)
LINE: 208.800003 153.143997 (0.000000 0.000000 1.000000)
LINE: 253.440002 188.351990 (0.000000 0.000000 1.000000)
LINE: 253.440002 188.351990 (0.000000 0.000000 1.000000)
In other words it seems the two highlighted lines should be replaced by a
point that is missing. Something like:
LINE: 119.519989 82.727989 (0.000000 0.000000 1.000000)
LINE: 163.500000 117.500000 (0.000000 0.000000 1.000000) ++
LINE: 163.500000 117.500000 (0.000000 0.000000 1.000000) ++
LINE: 208.800003 153.143997 (0.000000 0.000000 1.000000)
LINE: 208.800003 153.143997 (0.000000 0.000000 1.000000)
LINE: 253.440002 188.351990 (0.000000 0.000000 1.000000)
LINE: 253.440002 188.351990 (0.000000 0.000000 1.000000)
Could be an OpenGL driver bug, don't know.
Was this data from the very first time the print was attempted? It's not the
case that the print was done prior and the second time the alloc'ed gl2ps
feedback buffer was a slightly offset memory location, is it? (Trying to
discern if the ** lines above were actually written into memory or were
whatever happened to be in memory, which came from a previous print.)
