[vtkusers] Many VTK build tests fail when run from Jenkins/Bamboo or VNC display, even when DISPLAY is set to good opengl-enabled display

I've submitted a run here:
The list of failing tests is here:
I'll keep my fingers Xed... it'd be great if someone with more knowledge
could take a look at the list of failing tests and spot something they
have in common!
ps Re using VNC, for me it was an almost total failure, so i quickly
gave up and switched to sending the tests to my main Xorg/nvidia head.
Under vnc,the tests fail with an error message which says:
vtkXOpenGLRenderWindow (0x14251e0): GL version 2.1 with the gpu_shader4
extension is not supported by your graphics driver but is required for
the new OpenGL rendering backend. Please update your OpenGL driver. If
you are using Mesa please make sure you have version 10.6.5 or later and
make sure your driver in Mesa supports OpenGL 3.2.
It's odd, because it says i need mesa > 10.6.5 with GL version 2.1 but
I've got Mesa 17.2.4-2.fc27.x86_64, which provides "Max compat profile
version 2.1 and OpenGL > 3.2) and it still isn't happy. I think these
opengl features are just not supported on vnc, or not on my vnc
("llvmpipe" device, tigervnc server), or perhaps they are supported, but
i haven't worked out how to enable them. Maybe i just need to change the
"preferred profile, from "compat (0x2) to something newer.
