Rectangle should be transparent by default (unless you provide `fill`
argument explicitly).
'false' is not a valid color, so providing it shouldn't make any difference.
I suggest to provide color explicitly:
https://imagemagick.org/script/color.php

<https://imagemagick.org/script/color.php>
Here is red:
$bg->Draw(primitive=>'rectangle',stroke=>'red',points=>"100,100,980,980",
fill=>'#FF0000');
Black:
$bg->Draw(primitive=>'rectangle',stroke=>'red',points=>"100,100,980,980",
fill=>'#FFFFFF');
While
$bg->Draw(primitive=>'rectangle',stroke=>'red',points=>"100,100,980,980",
fill=>'#000000');
