Description Brody 2016-11-29 01:08:49 UTC 
I have a Qt app that I run remotely through ssh -X. I updated to the new MacBook Pro (MacOS Sierra) with TouchBar, which has a Radeon Pro 450, and now the app breaks with the following error:

X Error: BadValue (integer parameter out of range for operation) 2
  Extension:    149 (Uknown extension)
  Minor opcode: 3 (Unknown request)
  Resource id:  0x0
X Error: GLXBadContext 160
  Extension:    149 (Uknown extension)
  Minor opcode: 5 (Unknown request)
  Resource id:  0xa00033
X Error: 0 0
  Extension:    149 (Uknown extension)
  Minor opcode: 26 (Unknown request)
  Resource id:  0x0

The app DOES work with a 2015 Macbook Pro (which has no GPU) on MacOS Sierra, and it works on the TouchBar Mac when I use x2go. 

Thank you for your support,

I was able to get it to work again by downgrading to 2.7.8.

If you want to use IGLX in newer versions, you need to enable it:

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