Oh no! We already have more than a few thumbs showing ringing
artifacts. This is especially true for images which have jpeg
artifacting in their orignal. ..... Or is this like the off by one fix
below, something which has been in for a while but not something that
all the thumbs have caught up with yet?
* Some PNG and JPEG thumbs were sized a pixel off due
to mismatches in how
MediaWiki and ImageMagick rounded the resized aspect ratio; these could get
resized in the client, leading to extra blurry scaling
Wee! Wee!

librsvg 2.14.0
Cool. I need to upgrade my local copy.
Since invalidating *all* thumbs brought things to a
halt doing nothing but
rerendering, I've currently got it invalidating thumbs over a year old, and will
be moving up the cutoff date gradually over the next day or two.
Okay.
