If you use the new graphics system raster yes...the old one (x11) works as
before...
That the price of the speed to avoid X calls and to get something fast...I
repeat only the graphics system raster change that (NEW FEATURE)...Btw i
didn't find where it was written that QPixmap with X11 engine are for sure
XPixmap.
Quote from doc for graphics system raster :
"Since Qt 4.5, it is possible to replace the paint engines and paint device=
s
used for widgets, pixmaps and the offscreen double buffer."
