Libreoffice "insert hyperlink" blinking

Hello everybody,
I've been using Libreoffice Writer 3.5.7.2 to insert hyperlinks with "Destiny inside the document", to point to a text mark inside the document, and I see that when the little window with all the options to insert hyperlinks (such as tables, graphics, sections, text marks...), it blinks.
This is the window I'm referring to:


I'm not sure if it's a bug, it looks more like an initial refresh of possible "destinations in the document".
Is anyone experiencing this same glitch, or could reproduce it?

Thanks!
