 OLPC Version: 10.1.2 (XO 1.5)
 Activity Version: 15

 In the Paint activity, the menu items on the "Paint" menu pop up tooltips
 that fail to repaint the screen properly.

 I have not seen other activities do this, so I do not know if it is a
 problem with the Paint activity itself or a component underneath it.

 Reproduction:
 1. Start up the Paint Activity
 2. Click on the "Paint" menu to activate it.
 3a. Highlight any of the menu icons above the menu selector which have
 main menu selection items below them (the palette, color selector, zoom
 icons, etc.) until a tooltip shows.
 3b. Alternatively activate the border menu around the paint activity.
 4. Move the mouse so the tooltip disappears.

 Expected Results:
 The tooltip/border menu appears/disappears properly.

 Actual Results:
 - For 3a, an inverse refresh of sorts appears, where the part of the main
 menu item's label below the tooltip gets repainted properly, but not the
 part of the menu label which was not overlapped.
 - For 3b, all of the main menu labels (Activity, Paint, etc.) fail to get
 repainted, leaving blank gray selection buttons.

 Workaround: Selecting a new main menu area will cause all the menu labels
 to get repainted and appear onscreen.
