Upstream bug. Closing report.

What could be changed in Octave to fix this? This seems like an upstream bug with graphics drivers and possibly the distro that did the packaging (in this case Fedora).

I am running version 3.8.2 of Octave via 32-bit Fedora 21 on my old Toshiba laptop (Satellite A105-S4284, Intel Core Duo T2050 / 1.66GHz, 1GB of RAM). When I tried to run the Octave command contour (X, Y, pdf), Octave responded with the following two lines:
+vertbatim+
libGL error: Version 4 or later of flush extension not found
libGL error: failed to load driver: i915
-verbatim-

A Google search on the first line reveals the same error in another context:

I should add that a simple line plot works fine:
