Comment(by manuq):

 I have verified this is not a theme issue.  Our frame is composed by four
 gtk windows.  What happens is that when a window is moved, the previous
 area position is painted in the background color of the window below, for
 a small amount of time.

 For example in the Journal, the flickering color is grey, while in the
 activities list view, the flickering is white.

 The delay depends on the complexity of the window below.  For example in
 the Groups view with few friends, the issue is not so noticeable.  But in
 the Journal or in some activities like Abacus, it is.

 As a verification test, I opened Terminal, opened gedit, and started
 moving it's window over different Sugar places, like the Journal,
 activities list view, and activities.

 I have verified the issue is present at least since the latest 12.1.0 olpc
 build which has Sugar 0.96.2, so was present in GTK2 shell too.
