I am running IDL 8.5.1 on a Linux machine from a Mac client using X11 forwarding (ssh -XY ). Direct graphics works fine, but when I try to use function graphics, the plot window appears but I get an error message

IDL> p = plot(/test)
% WIDGET_EVENT: Failure to acquire window rendering context.
% PLOT: WIDGET_EVENT: Unable to acquire device context.
% Execution halted at: $MAIN$

I am running XQuartz 2.7.9 but I find the same problem with XQuartz 2.7.11 (after including the 2.7.11 fix https://groups.google.com/forum/#!topic/comp.lang.idl-pvwave /RM2K-0Dz6Lg ) Checking the comp.lang.idl-pvwave archives it appears the same problem appeared a few years ago with XQuartz 2.7.2

I have no problem with function graphics when not running remotely, on either my Mac or the Linux box. Thanks for any suggestions. --Wayne
