This example freezes on iOS iPhone 12 Safari right after the screen is touched and camera moves a bit:
I have been investigating on this bug for a week now in other setting and have to say this is rather mysterious! Hope someone would have some idea?
The code does not freeze if mesh is not removed or disposed (also it does not freeze on desktop). So, for some reason now there is a rather serious lockup situation on iOS when meshes are disposed nearby the rendering loop…
Edit: Now for a while this worked ok and then after 20 minutes started occuring again like in the video below.
