    Hi, i am running IDL on an iMac, that i access through ssh. I want to use X11 forwarding to display my results on my client machine, a macbook pro. When i run the example for xobjview, i have the following error: IDL> oSurf = OBJ_NEW('IDLgrSURFACE', DIST(20)) % Compiled module: DIST. IDL> XOBJVIEW, oSurf IDL> xp_destroy_surface: assertion failed: s != NULL xp_destroy_surface error: 3 % IDLGRSRCDEST::DRAW: Failure to acquire window rendering context. I used ssh -X to access the server, and xterm, xclock are working fine. The version of my os on the server: OS X Yosemite 10.10.3, xquartz 2.7.7 ,IDL 8.4.1. The version of my os on the client, OS X Yosemite 10.10.3, xquartz 2.7.7 ,IDL 8.4.1.

    Hi Pierre, Does it help if you force XOBJVIEW to use software rendering, for example: XOBJVIEW, oSurf, RENDERER=1 Frequently it can be difficult, even unfeasible, to use graphics hardware acceleration (RENDERER=1 -- the default keyword setting for XOBJVIEW) over a remote ssh/X11-forwarded connection. Regards,
