So, I was using CSG subtract for some operations which is working fine. I switched over to CSG2 and it totally broke my process for what I am doing. It isn’t totally broke, but the way I am using it the async is jacking it up. The meshes I am using are blinking when even I change the scaling of the mesh that was created with it.
How long can I use CSG before it is totally gone?
Maybe a reproduction of the issue in the playground could help devs to fix it
you have several years 
I do not plan to remove it any time soon so no stress

Basically, I am checking if the scale of a mesh has changed, then destroy it and rebuild it reactively. And there is a ms delay in the rebuild. Making it blink.
Have a try with csg.toVertexData().applyToMesh(mesh);, this does not require disposal of the original mesh
