<div dir="ltr">It is not a bug. We _require_ 3.2 when using the OpenGL2 rendering code and cannot function with a 3.0 context. Even though Mesa reports that it supports 3.0, it actually supports all of the 3.2 features that we need. So therefore, forcing Mesa to report 3.2 support is the best way to go. Otherwise, it would not be possible for us to create an OpenGL 3.2 context at runtime.<div><br></div><div>Also, note that your statement of "<span style="font-size:12.8px">Mesa 11.0.4 only returns version 3.0 by default" </span>is not entirely accurate. Mesa repots support for OpenGL 3.0 with the driver that you are building with, which is gallium-llvmpipe I am guessing. Other Mesa drivers support OpenGL 3.2 within 11.0.4, even earlier. These are hardware enabled drivers commonly used on Linux distributions. Unfortunately, gallium-llvmpipe is your only option currently for pure software rendering including OSMesa.</div><div><br></div><div>Best,</div><div>-berk</div><div><br></div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Nov 11, 2015 at 8:45 PM, Scott, W Alan <span dir="ltr"><<a href="mailto:wascott@sandia.gov" target="_blank">wascott@sandia.gov</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
