As far as I know, the bug is in expose_window (xdisp.c) and
what called from there.  And expose_window is triggered by
Expose or GraphicExpose events.  So, if Mac Cocoa uses
"backing store", such events doesn't happend, thus the bug
won't be revealed.  Isn't it possbile to suppress backing
streo on Cocoa?
