the code is very simple, copied from the tutorials of gtk

in one place of the program I declare the textView and the associated buffer:
 
my $view = Gtk2::TextView->new();
my $buffer = $view->get_buffer();
$view->set_size_request(850,500);
$view->set_editable (FALSE);
our $textmark = $buffer->create_mark('end_mark',$buffer->get_end_iter,FALSE);
my $scrolls = Gtk2::ScrolledWindow->new();
$scrolls->set_policy('automatic','always');
$scrolls->set_shadow_type('in');
$scrolls->add ($view);

on a function that run according to a specific button click I insert the text:

 #printing the output on textview
  my $text_tag = $buffer->create_tag(undef,'font',"Sans Italic 12",'foreground','#680000');
  $buffer->insert_with_tags($buffer->get_end_iter,"<$command_num>\n",$text_tag);
  $buffer->insert ($buffer->get_end_iter,$out);
  $view->scroll_mark_onscreen($textmark);

That's a strange behaviour.

Could you share some code?
