If i am gaussian blur for both dropdown/popup menus, i see no white at all. In situations where the white would normally appear - instead the menu quickly flickers (ie: i can visibly see the menu for a split second) then it disappears.
The rest of the time it works, as usual.
using blur is actually handy, because at least i am not getting white flashes on the screen.
One more detail.
