Comment (by stippi):
Normal drawing updates in Haiku are actually flicker free. When windows
are resized however, there are two mechanisms: The widgets get a new size,
and are requested to draw. When the widget has a background color set, the
app_server will pre-fill the exposed areas with that color. Widgets can
set a transparent view color to prevent that from happening. In addition,
some widgets request to be redrawn in full when they are resized. Perhaps
the process could be more optimized to prevent flickering, but when it
happens, it is due to these circumstances. The combination full update +
non-transparent view color should be the one that leads to flickering.
