Status: Confirmed => Invalid
Open/Closed: Open => Closed

Follow-up Comment #3:
I found the problem. The issue is that OpenGL itself only supports a limited
range of line widths. It has a range both for aliased (jagged) and
anti-aliased (smooth) lines.
I've attached code which will print out these ranges. Unfortunately it's in C
so you need to have the development packages for GL, GLU, and GLUT installed.
On Linux it compiles with
gcc -o rpt_lwidth rpt_lwidth.c -lGL -lGLU -lglut
In my case, the range of smooth lines is 1.0-5.0 and the granularity is 0.5 so
I can really have lines from 0.5-5.5 which explains the issue.
I don't think there's much to be done about this so I'm closing the report.
(file #31215)
