Stars malformed

Bugs
1

I am on the iPad 3 with retina.

When using a strokeWidth of 1 or 2 I can’t see the lines I draw

At 2.5 the lines look like a corner of a square

At 3 and above they are good.

I think the 2.5 looks neat but I’m not sure it is the desired look.

-- stars
function setup()
    
    displayMode(FULLSCREEN)
    createstars()
    checkagain = false
end

function createstars()
    star = {}
    for i = 1,250 do 
        rx = math.random(1,1200)
        ry= math.random(1,800)
        u = { x=rx, y=ry}
      table.insert(star,u)
    end   
end

-- This function gets called once every frame
function draw()
    -- This sets a dark background color 
    background(0, 0, 0, 255)

    -- This sets the line thickness
    strokeWidth(2.5)
    
  --  line(lx,ly,CurrentTouch.x,CurrentTouch.y)
  --  lx = CurrentTouch.x
  --  ly = CurrentTouch.y

     for a,b in pairs(star) do
        stroke(math.random(1,255),math.random(1,255), math.random(1,255))
        line(b.x,b.y,b.x,b.y)
     end
    -- Do your drawing here
    
    --print(math.abs(ElapsedTime))
    if math.fmod(math.floor(ElapsedTime),2)==0 then
        if checkagain then
            createstars()
        end 
        checkagain = false
    else
        checkagain =true
    end
end

This may be due to the smoothing function. See if adding noSmooth() before drawing the lines helps

Nosmooth() caused the stars to not be drawn at all…

But I’ll read up on the documentation and see if similar things exist.
