I hope you are doing well.
Since version 5.23.0: Release 5.23.0 · BabylonJS/Babylon.js · GitHub, I got a call stack size exceeded when I changed the render list of a render target:
VM3339:3 RangeError: Maximum call stack size exceeded at Proxy.hasOwnProperty (<anonymous>) at ArrayTools.MakeObservableArray (arrayTools.ts:86:62) at set renderList [as renderList] (renderTargetTexture.ts:81:28)
This render list is changed several times in render loop, so the bug appears after about 30 seconds of using.
I guess that it’s related to this commit: Fix scene not clearing in some Default Rendering Pipeline with multic… · BabylonJS/Babylon.js@5322d44 · GitHub
I hope that those information will help you.
Have a nice day !
