Disappearing search box in web interface

Using Chrome, when I want to enter some text in one of the search-fields in the web interface, I only manage to type a few letters before the field disappears. I can then move the mouse to the field and get the field back again, including the letters, and type a few more letters before the field disappears again.

Is there a way to make the search field more patient? And let me have something like 10 seconds to finish my text?
