did dpi get adjusted too? still 285dpi? check e's scaling settings. it can
adapt to dpi if it is set up to do so. it also has a manual scale switch to set
it to whatever u want. whatever e sets, elementary inherits too, unless the
theme has been done in such a way not to allow scaling (the default does).
custom written edje files with font may also not scale for the same reason a
different elm theme may not. if things are done right it should just magically
"work" on qvga and look wonderful.

as for display artifacts - maybe its a refresh issue or a screen timing issue.
not sure. i remember those screen artifacts long ago (like before freerunner
was even released). looks like nothing has been fixed since :)
