Good evening,
I get a black picture when rendering fragments with
glPolygonMode(GL_FRONT_AND_BACK,GL_LINE). Am I missing something, or is
it a bug?
There is a testcase here:
http://members.aon.at/~aklamme4/scratch/brk_line.c
And 3 screenshots showing the effects of GL_FILL,GL_LINE,and GL_POINT
respectively:

Does anyone see similar effects?
