This is probably not a bug now that 1.4 has been released, but since I am not quite ready to upgrade our live site yet, I have restricted our site to Discourse 1.4b9. However, when I rebuilt Discourse to add a plugin this week, a Discourse base image update (samsaffron/discourse:1.0.13) has brought a new version of ImageMagick with it that has left all my letter avatars vertically misaligned.
The end result is that all my letter avatars now look like this:
Prior to September 22, the ImagMagick version was 6.9.1-3 Q16 x86_64 2015-05-29, and after September 22, the version is now 6.9.2-3 Q16 x86_64 2015-09-22.
Can I downgrade ImageMagick in my container and rebuild the letter avatars, at least until I’m ready to go to the official 1.4 release?
For anyone following along, I’ve isolated the problem to this commit which fixes this reported bug in ImageMagick. I have no idea yet how to fix it, but I’m going to keep chipping away at it.
The issue is now fixed in ImageMagick’s git tree (as of 60001c3). There doesn’t appear to be a tarball release yet, but I’m sure there’ll be one soonish.
