Memory limit crash on iOS 26

I am running a heavy webapp in threejs, which worked fine on iOS 18. On updating to iOS 26, there is a crash when changing between large model files, that happens on no other platform. This seems to be associated with memory pressure - is anyone seeing a change in memory limits? WreckSploration VR

Relevant logs, with 2gb memory limit assigned after reload
