Bug Description

Sometimes, when launching Calibre, some of the covers (can be one, a few, or lots) appear very small (see picture). I am running Calibre 3.9 but I have noticed this bug since 3.7 at least. I am now running Calibre on MacOS Sierra 10.12.6

Is this a temporary thing? Are the covers always small or just on some starts?

Yes it does! I clicked on 'Larger covers' and switched from 'Auto' to something else like 4.0 x 5.3. Then clicked 'Apply' and the covers went back to normal (large) size.

I also went back to preferences and clicked 'Reset size' to bring it back to 'Auto'. The cover stay large, so that fixes it!

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
