Thanks for a pretty decent bug report, however what you are experiencing is unlikely to be related to the RenderTexture warning message you are seeing, rather it is much more likely that you are using a broken FreeGLUT version: This is a known issue with some distros and SuSE 10 in particular (as you probably would have noticed if you had searched this forum or the FlightGear mailing lists prior to posting, indeed the previous thread discussed exactly this problem). So, the general advice is to either simply downgrade your FreeGLUT version or to get the latest version from CVS (if you intend to keep using FreeGLUT that is). Alternatively, there is the possibility not to use FreeGLUT at all (GLUT or SDL are the alternatives).Concerning the RenderTexture warning: in general, this should not be critical. However, it may indeed affect the features that are available in FlightGear. Personally, I haven't yet seen this message occur with nvidia cards, thus I would assume you may either not be using the latest binary nvidia drivers or that something else in your OpenGL setup may be broken.
