I had the same bug. I've attached outputs for glxinfo and xdpyinfo.

Can you also please try the earlier pre-releases and indicate if they work or not?

I had the same problem and it seems that others are also facing this. I have tried all the betas like Jeremy said and only beta1 worked. Since beta2 I always got the same error message.

Hope this helps solving the bug...

Thanks

The main change in beta2 over beta1 was the version of mesa.  It's unfortunate that this wasn't seen by anyone over the over 8 months since beta2 was released =(

As a workaround for now, you can backup libGL.1.dylib from the 2.7.7 install and use it to replace the one in 2.7.8

As for why this is happening, is there a way you could get me access to IDL to help triage this?

Also, please add an update glxinfo output for the case of 2.7.8 with the libGL from 2.7.7, thanks.

DAVE (at https://www.ncnr.nist.gov/dave/download.html) is an open source application made with IDL, and I encountered the bug when I tried opening it. You might be able to see if the bug is fixed by running this program rather than having to install IDL.

I did the suggested test and it worked flawlessly. I used libGL.1.dylib from XQuartz 2.7.8 Beta1 and replaced on the installation of XQuartz 2.7.8. It was clear that libGL is the problem, so the question is, is there any way to solve this or those of us that use this version of IDL will have to always use the Workaround? In that case, how long "forever" might be? I mean, how long do you think we will be able to use the outdated version of libGL?

An for the glxinfo and xdpyinfo, I have no idea how I get those... If you tell me how, I'm pleased to get it for you.

I came to this bug because I need to run NASA SeaDAS 6.4 on MacOS.  This program provides a 32-bit IDL 7.0 runtime and 32-bit binaries including
an IDL interface, IDLshare.so.  I also have IDL 8.5, but it does not install
32-bit libraries and the release notes indicate that 32-bit operation is "unsupported".  I see this bug using the 7.0 (i386) runtime, but (after building a 64-bit IDLshare.so) not with IDL 8.5 (x86_64).  This causes me to wonder if this bug occurs only for 32-bit IDL sessions or has been fixed in current IDL versions: 

It could be useful to see the IDL banner:

It opened a window for the application as well as an xterm window with this console output:

Can you please explain to me how I use DAVE to trigger your error?
