Lightroom and Mac M1 RAM LEAKS - eating hundrets GB of RAM

Hi is this a known bug that Lightroom eats all the memory that M1 Mac has and then swaps it all the time? It can consume hundreds GB of RAM when editing photos. Is this fixable other than switching of GPU in Lightroom preferences? (the app is then very slow ...)

    M1 Studio with 128GB ram here, and Lightroom will eat up 95+GB and then stall. It's simply horrendous that one buys memory and ends up no better off than the LR-recommended 'minimum' amount.

      This is not normal behavior. Do you have any other software installed on this computer - especially things like antivirus, system cleanup apps, etc.? They are notorious for causing problems like this.

      No i dont. It is happening while using Lightroom Classic with switched GPU acceleration. Unfortunately without GPU on it is slow and laggy 😞  but RAM is not eaten in 100% and even more because it constantly swapping

      Yeah that is not normal at all. How much RAM do you have? 16 GB is the bare minimum for Lightroom but 32 is what you should have. Below 16 you will be swapping constantly but even then should still be fairly usable. Also is your operating system fully updated? Do you have enough free ssd hard disk space?
