So which minimal mesa version is required for paraview 5.3 ?<br></blockquote><div><br></div><div>It wasn't until Mesa 12 that OpenGL 3.2 was properly supported and reported by all Mesa drivers. With some versions of 11, though, it works *enough* that you can fake it by exporting the environment variable GL_VERSION_OVERRIDE=3.2, so give that a try. If you instead want to just use the linux binaries from <a href="http://paraview.org" target="_blank">paraview.org</a>, we build those on EL6 and include a very recent copy of mesa with it that you can make paraview use with:<br></div><br></div><div class="gmail_quote"><div style="margin-left:40px"><span style="font-family:monospace,monospace">paraview --mesa-swr<br></span></div><br></div><div class="gmail_quote">That instructs ParaView to use it's own copy of Mesa and the OpenSWR parallel CPU rasterizer.<br><br></div><div class="gmail_quote">- Chuck<br></div><br></div></div>
