So I’ve recently notice odd RAM usage in editor. This happens when I’m working on a tab other than the main viewport for a longer period. The longer the viewport is inactive the worse it gets. If I keep the editor Idling It will become unresponsive. If I reopen the editor the RAM returns to normal. This is really strange because if I’m actively using the viewport nothing like this happens.
Here are some images.

Note: The level is very simple and does not have many complex meshes nor particle effects except snow particle system but its lifetime is set to 20 sec for the emitter.
