The right-aligned icon strip is positioned against the viewport rather than
the row, so the pixels a blit scroll reuses are stale and the icons leave
ghosts behind. Scroll the viewport in simple mode, and widen every repaint
request to the full visible width so a row whose label changes size cannot
leave its icons behind either.
Also stop blacklisting an icon whose download failed only because the file
transfer channel was not up yet: channel rows are painted during connect,
well before that point, so their icons would never be retried.
