 Enable render caching in qgis options, then add a vector layer (I always
 use the "world borders" shape to make such tests) and then add the layer
 to the overview.

 Many times, but not always, the overview immediately goes wild showing a
 wrong extent. If you then try resize the overview window it seems to fix
 the problem, but then you can notice empty spaces between the countries.

 If the overview doesn't go immediately wild you can do the following:
 change symbology to the vector (old or new symbology doesn't matter), then
 remove the vector from the overview and add it again (to see the overview
 with the new symbology). Now the overview goes wild.
