[Octave-bug-tracker] [bug #63849] Crash when plotting dotted line using system OpenGL

[Markus Mützel]

Follow-up Comment #4, bug #63849 (project octave):

Like I wrote somewhere else, we are unfortunately in a situation where Octave
can crash with the software or with the hardware OpenGL drivers. That seems to
depend on the system on which Octave is executed.
The actual reason might be some timing issues between different threads. It
might be that it just so happens on some systems that the relevant functions
are executing in a "good" order and on other systems in a "bad" order with
either the software or the hardware OpenGL renderers.
For the time being, the best we can do imho is to advice affected users to
test if updating their graphics drivers makes a difference. (The timing might
just be so different that the relevant functions happen to execute in a "good"
order.) Or if that doesn't work switch from hardware to software renderer (or
vice versa).

Since both renderers could lead to Octave crashing on some systems and the
hardware renderers are orders of magnitude faster (if they are working), I'd
vote for keeping the hardware renderer the default in the installer.
