I have a MAC OS Sierra 10.12.1 and downloaded Xquartz 2.7.11. IDL graphics was ok until I tried their DEMO program, which crashed.
Then I tried ENVI (an IDL sister) and it would start up and die.
Both worked before ugrading Xquartz today.
I went back to a previous Xquartz (2.7.7) and everything works fine.
There's not enough information here to act on. If you're using IDL remotely, you need to enable IGLX with:
defaults write org.macosforge.xquartz.X11 enable_iglx -bool true
