yes running the application locally causes no problem.
btw, the same application compiled with an older version of openframeworks,
compiles and runs fine. in this case, the output (where the other halts) is:

bummer, to get the openframeworks application working you'll need to
install some stuff. I'd advise against it. If you want to though, here are
the instructions: http://openframeworks.cc/download/
grab a version of codeblocks IDE and openframeworks 0.8.4 and install
according to instructions in here
http://openframeworks.cc/setup/linux-codeblocks/
Since the problem does not appear with openframeworks 0.8.1 but it appears
in 0.8.4 (not sure about .2 and .3 releases), i was going through the
changelog to see if they have altered something significant in opengl. I
can't see anything
https://github.com/openframeworks/openFrameworks/blob/master/CHANGELOG.md
I have asked in their forums too :
http://forum.openframeworks.cc/t/executing-opengl-applications-remotely-using-vglrun/17870
haven't got a reply yet though...
If you choose to install openframeworks, please let me know and i'll send
the sources over.
Thanks
