So finally, after some back and forth, the support tech was able to reproduce the problem, so now this is a known bug at maxon! - but resolution time will depend on the amount of users affected. So if you also have this problem, please go to https://www.maxon.net/en/support-center , select Support Requests, and choose 'I need technical support' from the dropdown, and explain the memory leak briefly to maxon (including the Redshift render failure issue), letting them know you have also seen other users with this problem. Together, strong!
