Hi,

A colleague of mine is experiencing problems with Xquartz 2.7.8 and IDL 
<http://www.exelisvis.com/ProductsServices/IDL.aspx 
<http://www.exelisvis.com/ProductsServices/IDL.aspx>> both under Yosemite or El 
Capitan.
The IDL application stops with the strange error message:
> No matching pixelformats found, perhaps try using LIBGL_ALLOW_SOFTWARE
> Abort trap: 6

I found that this message is described here 
<http://lists.freedesktop.org/archives/mesa-commit/2014-May/049872.html 
<http://lists.freedesktop.org/archives/mesa-commit/2014-May/049872.html>>
I also found a related bug report : 92642 dated 23 oct 2015

The bug occurs with
IDL 8.1 applications and Xquartz 2.7.8
on the web users report that the problem also exist with IDL 7.1 or 8.2
No problem with
        IDL 8.5 and Xquartz 2.7.7
        IDL 8.5 and Xquartz 2.7.8

Is there any news about that bug or any workaround except installing Xquartz 
2.7.7 instead of 2.7.8 ?

All the best

Linus
