 This bug has been observed in multiple versions of fgfs,
 including one compiled back in May, 2006 as well as
 the most current CVS version.
+This is 100% reproducible with a
+ATI RV350 [Mobility Radeon 9600 M10] chipset
+and the ati-fglrx driver.
+The leak is observed whether or not
+OSG_GL_EXTENSION_DISABLE=ATI:GL_SGIS_generate_mipmap is set.
