Camera enabling/calling Camera.Render() extremely slow, generates a lot of garbage

Essentially the same as the title. This is an ongoing issue with the HDRP's rendering system; Enabling a disabled camera generates a gigantic amount of garbage and causes significant frame drops, while calling camera.Render() causes those same drops every single frame.

They appear to be related to the re-creation of a virtual camera (HDCamera). Is there any way to prevent these virtual cameras from being destroyed in the first place?

 

Hello! Were you able to find a workaround?
