I did an A/B test with this fixed 5.4 app and the app built from 5.2 and can not see any difference in the basic performance using the sample HandheldAR project.
It would be great to get this fix into the next point release of 5.4. I know there are plenty of folks out there who are not going to be comfortable modifing the ARKit plugin source code and rebuilding the plugin on their own.
Folks can attempt to download and use my modified version. You need to place it in your project’s Plugins folder. Warning, this doesn’t seem to work for everyone as I can’t properly sign the binary files.

Oh, one more thing for everyone, it looks like the legacy Xcode workflow is broke in 5.4 as well, so you’ll need to use the Modern Xcode workflow to build dev and shipping apps.
thanks again
