Even though the "time" icon looks allright in the "Total raw" line due to the inserted text,
You can see that the top "time" icon is much closer to the top than to the bottom.
Thanks for the report. That actually comes from the nature of that picture (the icon itself has a very slight shadow) and the way our crop caching works. We have started revisiting all the icons and this one is still a placeholder. Therefore putting this to minor for now.
