This one is kind of hard to notice, but makes setting widgets confusing. The grid that's displayed next to the widgets when in editing mode (not the grid on the desktop, the one next to each widget in the selection box) displays all widgets as 1x1, no matter what size they are. If the widget name gets cut off (see gTabSimiClock in the screenshot), it's almost impossible to tell how big the widget will be if you haven't memorized their placement.
