Works fine on Vagrant with Thumbor. Odd...

Production Thumbor servers run Ghostscript 9.06 (2012-08-08) which is very outdated, because it's on Jessie. Vagrant is on Stretch now, which has Ghostscript 9.20 (2016-09-26). Upgrading ghostscript is all that should be required here.

FYI, Ghostscript on the Thumbor servers got upgraded to 9.26, worth retesting.

Looks fine to me now, please reopen and give us a link to a specific thumbnail if you still see broken ones.
