I didn't have this feature enabled and I didn't see this bug. It does show up but with black font in the black background.
I upgraded the zip file by moving it above the SMF copyright.
If you want to fix it yourself, you can modify the font or the background color in style.css or like I did:
In index.template.php find and delete this code:
// Show the load time?
if ($context['show_load_time'])
echo '
<div align="center" class="smalltext">
', $txt['page_created'], $context['load_time'], $txt['seconds_with'], $context['load_queries'], $txt['queries'], '
</div>';
}
function template_html_below()
{
global $context, $settings, $options, $scripturl, $txt, $modSettings;

echo '
<div id="ajax_in_progress" style="display: none;', $context['browser']['is_ie'] && !$context['browser']['is_ie7'] ? 'position: absolute;' : '', '">', $txt['ajax_in_progress'], '</div>';
find:
<a href="' . $scripturl . '">', $context['page_title'] != "$context[forum_name] - Index" ? "$context[forum_name] - " : '', $context['page_title'], '</a><br />add right after:
';
// Show the load time?
if ($context['show_load_time'])
echo '
<div align="center" class="smalltext">
', $txt['page_created'], $context['load_time'], $txt['seconds_with'], $context['load_queries'], $txt['queries'], '
</div>';
}
function template_html_below()
{
global $context, $settings, $options, $scripturl, $txt, $modSettings;
// The following will be used to let the user know that some AJAX process is running
echo '
<div id="ajax_in_progress" style="display: none;', $context['browser']['is_ie'] && !$context['browser']['is_ie7'] ? 'position: absolute;' : '', '">', $txt['ajax_in_progress'], '</div>';
echo '
