If you compile from sources you could try to re-activate the XSync based paint
defer.
it 's around composite.cpp:416

#if 0
    // skip windows that are not yet ready for being painted
    ToplevelList tmp = windows;
    windows.clear();
    // There is a bug somewhere that prevents this from working properly
(#160393), but additionally
    // this cannot be used so carelessly - needs protections against broken
clients, the window
    // should not get focus before it's displayed, handle unredirected windows
properly and so on.
    foreach( Toplevel* c, tmp )
        if( c->readyForPainting())
            windows.append( c );
#endif

it has been disabled for bug #160393 but the XSync protocol implementation was
broken before 4.6 anyway (and actually doing it (hopefully) right now might
cause this bug)
