opengl2_h_mirrors_bug

With OpenGL2 enabled mirrors aren't working anymore.

Esay to reproduce: start a map with a mirror texture, e.g.: q3dm8, q3tourney6.
As soon as you enter the area with the mirror a HOM effect will appear (some world brushes will disappear and the place where the mirror is will get blurred).

The attached screenshots shows the ceiling mirror in q3dm8 and the floor mirror in q3tourney6.

Sidenote: I'm not sure if only 'horizontal' mirrors are affected. q3dm0, with a 'vertical' mirror seems to work correct (last picture on the screenshot)

I'm on Win8 64-bit Nvidia Gforce GTX 770 (latest driver version)
