Although things are much worse under Qt, there are actually some artefacts too
under X11, especially when scrolling.  I slightly improved the situation
(see my recent commits in Plugin/X11), but I do not manage to get everything
correct; arbitrary non integer shrinking factors remain quite problematic;
some rendering assumptions seem to be subtelly broken.

In any case: Max and Miguel, please investigate what can be done for
the Qt version. Is there anything I can do in order to improve things?

Best, --Joris
