solved, 
as a memory for the future:
in Mer, Qt is patched setting 
 view.setAttribute(Qt::WA_OpaquePaintEvent);
 view.viewport()->setAttribute(Qt::WA_OpaquePaintEvent);

on all qgraphicsviews, that makes a small performance gain on opaque windows, 
but of course has to be explicitly disabled if you need an argb one.
