This is a continuation of the issue found https://bugzilla.redhat.com/show_bug.cgi?id=2170830#c52 

Sample program to reproduce the issue:

#!/usr/bin/perl
use strict;
use warnings;
use Tk;

# Create the main window
my $window = MainWindow->new;
$window->title("Input Dialog");

# Create a label to display the instructions
$window->Label(-text => "Enter your input:")->pack;

# Create an entry widget to input the text
my $entry = $window->Entry->pack;

# Create a button to submit the input
$window->Button(
    -text    => "Submit",
    -command => sub {
        my $input = $entry->get;  # Get the input from the entry widget
        print "Input: $input\n";  # Print the input to the console
        $window->destroy;         # Close the window
    }
)->pack;

# Run the Tk event loop
MainLoop;
