[tmodes <1362170@xxxxxxxxxxxxxxxxxx>]

The patch applies to the freeglut source (it is accessing some internal
variables which are not accessible from outside.). So would apply the
patch to the freeglut sources and recompile freeglut and install the new
compiled freeglut.


PS: There is a second bug report with a similar problem. But noone from the freeglut team responded to it: http://sourceforge.net/p/freeglut/bugs/201/

  Driver used : ati-drivers-14.6_beta1
  on another exemple, OpenCL on my computer is working great (much faster than via the pcu ) via darktable
  Debug information from darktable :  ( if it's can help ) 
  [opencl_init] device 0 `Tahiti' supports image sizes of 16384 x 16384
  [opencl_init] device 0 `Tahiti' allows GPU memory allocations of up to 1024MB

  Don't known how to provide more information :
  - I have recompiled higin with debug information (no more information in the GUI)
  - don't known how to test nona from the commande line
