Sure, I’ll drop the info here as soon as I have any news.
In the meantime, another issue with 4.23: When you have a large landscape with tessellated material, it takes much longer to load after hitting Play. In 4.22 the same setup loads in 1-2s, in 4.23 it takes 7-8s on my end. I’ve reported that with an example project & repro steps, if you want to test if your project is affected: https://imgur.com/a/MUWJRyq
