Opengl outline font in conflict with textures_问答_开发者

I want to render outline font near playing area, but these two parts are in conflict. If I render only outline font, it's ok. When I render also playing area, textures of cubes have defect and light is changed also. When I render only playing area, it's ok. Here are some pictures: http://img.obrazok.com/Untitled.usdh.png

If you have some question or want see another part of code, just ask. Thank you.

The documentation for wglUseFontOutlines at MSDN says this:

With WGL_FONT_POLYGONS, the created display lists call glFrontFace( GL_CW )
or glFrontFace( GL_CCW ); thus the current front-face value might be altered.

OpenGL defults to GL_CCW; so chances are, if you set it back with
