Was there ever a resolution to this? I found this old tracker item: https://sourceforge.net/p/virtualgl/bugs/22/
that seems to confirm that, at least in older versions of ANSYS, running applications through the launcher stomps on LD_PRELOAD somehow. It was supposed to be fixed in 14.5, but maybe it got reintroduced, or perhaps it was never really fixed for Fluent. The real mystery, though, is why Nathan can't repro the issue. Nathan, is it possible that the application is falling back to client-side OpenGL rendering, which I'm given to understand is supported in ETX (but isn't supported in TurboVNC)? In your testing, did you enable VGL_LOGO to verify that VirtualGL was active? In any sense, if this issue is caused by the launcher stomping on LD_PRELOAD (which does appear to be the case, based on reviewing the recording), then there is unfortunately very little I can do about it. The bug tracker above mentions that someone was able to get around this issue by launching an xterm using vglrun and then launching ANSYS (without vglrun) from within the xterm, but I fail to understand why that would make a difference.
