The rendering of my emacs fonts changes if I define a specific list of directories under the LD_LIBRARY_PATH environment variable just before I call emacs. I changed this because I wanted to use emacs to debug a specific program that requires some of the libraries in the path, but I wasn't expecting the emacs fonts to change. What could be causing this effect on my emacs fonts?
I get this warning:
emacs: /somewhere/libpng12.so.0: no version information available (required by emacs)
