Public bug reported:
With shimmer-wallpapers installed, xfdesktop-settings suffers long freezes
completely hogging one core while regenerating a thumbnail list or selecting an
SVG image.
The apparent reason is that the present renderer is incapable of handling
high-quality SVG files included along with PNG fast enough: it takes 30 seconds
from selection of bluebird-2010-08-xubuntu.svg to changing the wallpaper where
PNG images change instantly and even Aquarius.svg (xfce4-artwork) takes about
half of a second.
Same result with some viewers in /usr/share/wallpapers - of course, it would be
good to have all viewers and previewers more vector-friendly, but since right
now it's not the case, the end result is: wallpaper chooser becomes almost
unusable.
