:mossop, could you have a look please?

Don't see what could be wrong here from the glxtest side apart from https://searchfox.org/mozilla-central/source/toolkit/xre/glxtest.cpp#1209 - and that's been around since forever. So to me this looks like an issue on the setup side, probably the X server crashing for some reason.

I get this message locally when I run with --headless mode over an SSH connection. It looks like the log linked in Comment 0 is also --headless. The actual test failure here seems to be do to intermittent network issues with NPM though.
