Since the latest updates to auras it seems to take a while before aura durations are displayed when buffs are applied after login/reload. Also, this has been happening since earlier, but often after login some buff durations on people aren't displayed whereas others are.

oUF doesn't do aura durations, so this is most likely an issue with a
layout or a plug-in.

Right, that was pretty stupid of me. Some part of me linked durations to oUF after those updates.

Just to let you know: I am slightly interested in what change(s) made it act that way. Main reason for this is really that I'm contemplating if I should write a oUF 1.5 -> 1.6 proxy.

Tested a little and found it's because of the removal of these 2 lines in createAuraIcon:

button:SetWidth(icons.size or 16)
button:SetHeight(icons.size or 16)

A lot of cooldown scripts (used to) work with GetWidth() or GetSize(), so maybe it's just time to move on from that.

Yeah, that just sound like a bad solution on their part. Anchoring should really be used to solve that.
