Upgrade from 2.28.2 to 2.31.0 seeing crashes

[yliu342]

Hi, we've recently upgraded from 2.28.2 to 2.31.0 and start seeing multiple crashes. I've attached some crash logs.
We are using SwiftUI and all crash are on iOS/iPadOS 26.0+. I suspect that these crashed are related to work on support perspective skew correction in 2.29.0 which in that commit the cropView get a big rewrite and somewhere that there is a missing handling of NaN frame or zoomLevel.

I’ve just released Mantis 2.31.1. I added some defensive checks—could you please test it and see if you can still reproduce the crash you encountered earlier? Thanks!

Hi, thanks for the quick response. We've released a hotfix for our app which downgrade to 2.28.2 but we will try upgrade to the latest 2.31.1 in our next release.

On my end, I'm not able to reproduce any of the crashes myself so that's why it is a bit hard for me to verify your fix.

Just wanted to follow up — Have you noticed any improvements regarding the crashes? Have there been any new crash reports so far?
