 g.region (g.region rast=elevation) and it is the same.

 Hmm.. Please enable line 221 (this line works as expected. reporting the
 correct viewport size).

 Test 1: line 148. change GL_TEXTURE_2D to GL_TEXTURE_RECTANGLE_EXT

 Test 2: Keep GL_TEXTURE_2D in line 148 and change size=640,480 to
 size=512,512 (power of 2 for GL_TEXTURE_2D).

 I know the original reporter already tried these, but without line 221.
