OpenGL 1.1 + SDL2 + SDL_TTF Text Render Transparency - c++

Question

I'm trying to write simple gui in c++ with opengl+sdl2, but now I have problem with text rendering.
This is what I get on my old laptop with opengl 1.1(notice white rectangle):
and this on my pc:
This is my function for text rendering:
void drawText(std::string text,TTF_Font * font,GLubyte R,GLubyte G,GLubyte B,GLubyte A,float X,float Y,float Z=0){
SDL_Color color={R,G,B,A};
SDL_Surface *msg = TTF_RenderUTF8_Blended(font,text.c_str(),color);
GLuint texture=0;
glGenTextures(1,&texture);
glBindTexture(GL_TEXTURE_2D,texture);
GLuint texture_format;
int wW,wH;
SDL_GetWindowSize(window,&wW,&wH);
int colors = msg->format->BytesPerPixel;
if (colors == 4) { // alpha
if (msg->format->Rmask == 0x000000ff)
texture_format = GL_RGBA;
else
texture_format = GL_BGRA_EXT;
} else { // no alpha
if (msg->format->Rmask == 0x000000ff)
texture_format = GL_RGB;
else
texture_format = GL_BGR_EXT;
}
float MsgWP=msg->w*1.0/wW;
float MsgHP=msg->h*1.0/wH;
int dX=-1;
int dY=1;
X*=2;
Y*=2;
glTexImage2D(GL_TEXTURE_2D, 0, colors,msg->w,msg->h,0,texture_format,GL_UNSIGNED_BYTE,msg->pixels);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glEnable(GL_TEXTURE_2D);
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA);
glBegin(GL_QUADS);
glColor3f(1,1,1);
glTexCoord2f(0,0); glVertex2f(dX+X+0 , dY-Y+0);
glTexCoord2f(1,0); glVertex2f(dX+X+MsgWP , dY-Y+0);
glTexCoord2f(1,1); glVertex2f(dX+X+MsgWP , dY-Y-MsgHP);
glTexCoord2f(0,1); glVertex2f(dX+X+0 , dY-Y-MsgHP);
glEnd();
glDisable(GL_TEXTURE_2D);
glDeleteTextures(1,&texture);
SDL_FreeSurface(msg);
}
Now I have a question: Why on lower version of opengl text is not rendering correctly?
