Same problem as with version 2.7.9

You haven't provided any information on the issue, and glxgears seems to be working fine.

Hello Jeremy,

Sorry my computer rebooted and I could not add more details. The problem with glxgears manifests itself when connecting (with X-forwarding enabled) to a remove host (particularly to a cluster running CentOS 6.8). Glxgears works locally with version 2.7.10 but it does not work remotely, albeit other XWindows functions do work (xclock, xterm, etc.).

Downgrading to 2.7.8 fixes the problem.

Any idea how to fix this?

Thanks,

Raffaella.

defaults write org.macosforge.xquartz.X11 enable_iglx -bool true

Hi,

I am trying to use ssh X forwarding to run some image processing software on our compute machine running Ubuntu 16.04. While 2D apps work fine, I am unable to run anything using 3D rendering. I am using XQuartz 2.7.11. I tested 3D rendering capability with glxgears:

$ uname -a
Darwin IHU-HASSA-MP002.local 17.2.0 Darwin Kernel Version 17.2.0: Sun Oct  1 00:46:50 PDT 2017; root:xnu-4570.20.62~10/RELEASE_X86_64 x86_64
$ defaults read org.macosforge.xquartz.X11 enable_iglx

$ glxgears
340 frames in 5.0 seconds = 67.977 FPS
$ ssh -X ubuntu-machine
ubuntu:~$ uname -a
Linux IHU-HASSA-LF001 4.4.0-97-generic #120-Ubuntu SMP Tue Sep 19 17:28:18 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
ubuntu:~$ glxgears
Error: couldn't get an RGB, Double-buffered visual
ubuntu:~$ echo $DISPLAY
localhost:10.0
ubuntu:~$ exit

I was unable to find anything on glx and Xquartz on the web except for this bug and it seems the issues might be related.

Did you actually set the preference to enable IGLX as indicated in the comment immediately preceding yours?  If so, file a new bug report.
