DynamicRenderer always printing with transparent background

[Vaibhav Chauhan]

Describe the bug

I'm implementing a box which contain text and if there are are more text line then the box height then text will scroll up. But the thing is when I print text with spaces it is ignoring the space

To Reproduce

    def __init__(self,height,width,text):
        super().__init__(height,width)
        self.text=text
        self.height=height
        self.width=width
        self.x = 0
        self.y = 0
        self.buf = [[' ' for _ in range(self.width)] for _ in range(self.height)]
        self.text_len=len(self.text)
        self.pos=0
    def _render_now(self):

        self._clear()

        if(self.pos>=self.text_len):
            while(self.x<self.width):
                self.buf[self.y][self.x]=' '
                self.x+=1
            return self._plain_image,self._colour_map
        c = self.text[self.pos]
        
        if(c=='\n'):
            while(self.x<self.width):
                self.buf[self.y][self.x]=' '
                self.x+=1
            self.pos+=1
            return self._plain_image,self._colour_map

        if(self.x>=self.width):
            self.x=0
            self.y+=1
        
        if(self.y>=self.height):
            self._clear()
            for i in range(self.height-1):
                    for j in range(self.width):
                        self._write(self.buf[i+1][j], j, i)
                        self.buf[i][j]=self.buf[i+1][j]
            self.y=self.height-1
            for i in range(self.width):
                self._write(' ', i, self.height-1)
                self.buf[self.height-1][i]=' '
            #self.y=self.height-1
            
        
        self.buf[self.y][self.x]=c
        self._write(c, self.x, self.y)
        self.x+=1
        self.pos+=1
        print(self.buf)
        return self._plain_image,self._colour_map

    def _write(self, text, x, y):
        self._canvas.print_at(text, x, y,colour=0,bg=7,**transparent=False**)

text='''line    1
line   2
line   3
LINE....4'''

Print(screen,textbox(3,10,tt),10,100,speed=2)

Expected behavior
As you can see in the screen shot there are black gaps which are spaces but should be white

That code is fine. I suspect your issue is actually what you're using to display the renderer is using the wrong style.

The logic is that the Renderer uses a Canvas to create its content, then some Effect prints the contents of your Canvas to the Screen. Assuming you're using the Print Effect, you need to pass in transparent=False to that effect.

If you're using a different Effect, check how it passes the transparent option to print_at().

Thank you for reply.
It worked after setting the transparent=False.
Thanks a lot...
