And we should check what happens if somebody runs this with an open-source
driver with a releases Xorg server. The log message only indicates that
with Xorg <1.6 the preview-rendering might not be accelerated, but from my
past experience with XRender on open-source driver (ati) I'm suspecting
that people not fulfilling that requirement might even get broken rendered
previews.
