Update of bug #52584 (project octave):

              Item Group:                    None => Performance            
                  Status:            Works For Me => Confirmed              
                 Summary: octave hangs after print => Printing with many
markers is very slow


Follow-up Comment #4:

I can confirm that printing with a large number of markers is very slow. On my
computer though, with the address sanitizer enabled and debug symbols, the dev
version is much slower than what you report: ~320s with either "o" or ".".

Unfortunately, each marker is drawn using a fixed number of lines, that
depends on the marker type, and/or with an undefined (opengl driver dependent)
number of triangles. With this approach, I can't see any easy improvement
since gl2ps will always have to treat (eventual depth sort/write) each
