weird alpha during pause?

[Makkeonmies]

Hey, so I implemented pause in my game with following codes:

obj_pause:

Create

paused = false;
scrn = -1;

Alarm 0

scrn = sprite_create_from_surface(application_surface,0,0,surface_get_width(application_surface),surface_get_height(application_surface),0,1,0,0);
instance_deactivate_all(true);

Step

if(keyboard_check_pressed(vk_f3))
    {
    paused = !paused;
    if instance_number(announcement_displayer)>0{
    ds_queue_clear(global.notificationQueue);
    announcement_displayer.showingNotification = false;}
    alarm[0]=1
    }
if !paused{
if sprite_exists(scrn){
        sprite_delete(scrn);
        instance_activate_all();
    }
}

Draw Gui

if paused{
if sprite_exists(scrn){
    var w = display_get_gui_width(), h = display_get_gui_height();
    draw_sprite(scrn,0,0,0);
    
    draw_set_halign(fa_center);
    draw_set_font(font4)
    draw_text_outline3(view_wview/2,50,"Paused",c_white,c_black);
}
}

The Alarm exists cause I had problems before with making texts disappear from screen when pausing the game. It works fine when I make the texts disappear before the alarm event plays out and then the surface is drawn and all is deactivated, so thats working good, for some reason didn't work when the code in the Alarm event was displayed at the end of the current code in Step.
Now tho, a weird alpha appears when i pause the game; it makes everything a bit transparent, and it just looks real silly, especially since some objects (ones with their sprites being blurred from the edges for example) really show the transparency.
Any ideas why its happening?

thanks beforehand!

SOLVED! all i had to do was:

draw_enable_alphablend(false);
draw_sprite(scrn,0,0,0);
draw_enable_alphablend(true);

alter the part of Draw event in this way.
