In functions texstore_rgba_fxt1 and texstore_rgb_fxt1(texcompress_fxt1.c), calling _mesa_compressed_image_address with mesaFormat set to GL_COMPRESSED_RGB_FXT1_3DFX or GL_COMPRESSED_RGBA_FXT1_3DFX. From the context, it is a mistake. Here it should pass a Mesa internal format, or it will trigger a mesa error. 107 dst = _mesa_compressed_image_address(dstXoffset, dstYoffset, 0, 108 GL_COMPRESSED_RGB_FXT1_3DFX, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 109 texWidth, (GLubyte *) dstAddr);
