Please describe the problem:
Any combobox (with lots of items) which has to show a pager button (or whatever
the arrow thing is called) shows some kind of drawing bug.

If the current selection of the combobox is near the beginning or the end of the
list and the combobox must be drawn for the first time, then half the list is empty.

If you scroll the list in either direction, the items become visible one by one
and can be selected. Once every item is shown and the whole combobox is drawn
like it should be, then the problem does not show up again. It only happens on
initial drawing.

I've attached two screenshots showing this behaviour. The drawing bug happens on
both ends of the list and shows up in all applications. The screenshots are
taken of Epiphany.

It happens with most themes I've tried. So it's likely to not be a theme engine
problem.

Does this happen every time?
Yes, if the combobox has enough entries to hit the edge of the screen.
