@dlonie @jbeezley @sankhesh @aashish24 any idea why these 3 test fail when enabling mesa?

I'm going to turn them off in case of RH/MESA

@doutriaux1 it seems to that on this machine volume rendering is not working. What version of MESA are you using on this system?

@aashish24:

[user@ocean ~]$ glxinfo | grep "OpenGL version"
OpenGL version string: 2.1 Mesa 10.4.3

[aashish24]

Recently I found out that Mesa 10.5.5 or later is better. Is this Mesa installed by our superbuild?

[jbeezley]

I have seen the same issue with mesa on Ubuntu as well.

[doutriaux1]

We are installing 7.1 should I try to upgrade?

[jbeezley]

Someone (maybe @cjh1?) told me a while back that only specific versions of mesa work with VTK. I have never tried though.

[durack1]

@aashish24 nope, looks like 7.6.1:

Looks like 11.0.0 is now available

[aashish24]

It used to be 7.* some version and while it may be still true for VTK OpenGL 1 backend, 10.5.5. is minimum for OpenGL 2 version (which we should switch to in 6 months - year). If we can try 10.5.5 for OpenGL 1 version of VTK (which we have right now), it would be great.

got it to pass all test except the one from BUILD_MODE=ALL, merging.
