Broken in 2.7.9 beta 1
Reverted back to 2.7.8 and problem went away again.
BTW, installers in 2.7.9+ were all super slow compared to 2.7.8

To me it still sounds like "Chinese" but I will transfer that to the people that may know more in my Department and if I hear back anything helpful I will let you all know. I hope I will convince someone to look into this so that we all benefit. The thing is that perhaps for us to try on El Capitan 10.11.4 an older XQuartz may be hard because I think that the first version that supported El Capitan was 2.7.8, just one version before and have no idea if this would even work. I can certainly try though at least with that version or I could find someone who has an earlier mac model to try more versions. This may take some time though. In the meantime I will see if I could get us some help. If anyone has any ideas please share here. Thanks!

>>> Given that the issue is with indirect rendering, it is either a change in xorg-server in XQuartz or a change in libGL or the X11 stack on the remote system. My hunch is that the remote libGL changed and possibly something in XQuartz's IGLX support changed. If you can try running older versions of XQuartz to see if it works with an older version of XQuartz, that might point to a change that could be made to get this working again. Although as I mentioned, IGLX is on life support in general, not just in XQuartz.

I have also asked in the bugzilla for xquartz reporting this and they did reply to me (https://bugs.freedesktop.org/show_bug.cgi?id=93953#c6) but the response was basically that if I am not a coder or a developer does not step up there is not a chance that someone will be looking into that problem for a fix to be developed. I asked again there to what end the problem lies, meaning whom I should be bothering about this because it is clearly something that relates to Mac computers (i.e. apple, xquartz, etc). I am still waiting for that but will get but to you with any updates. I doubt it though if they will say anything helpful. If anyone knows something about that please share! Thanks!
>>>>> Yeah, as I mentioned in the bug report, there's not much chance of things like this getting fixed soon because there aren't many people working on the project. I have maybe 2-3 hours every month or so, which is about just enough time to pull in security fixes, do some testing, and send out an update. Adding support for OpenGL Core in our direct rendering path is more work than I can sign up for. What you are asking for is adding it to the indirect rendering path, and that's even less likely to ever happen. Xorg is actively deprecating AIGLX and even removing it from the default configuration, so I suspect the solution there will be to just remove support for AIGLX completely.
