Same here. Excessive memory usage when streaming a lot of data in my browser (in this case watching the camera feed of my 3D printer / octopi).
It keeps stable for a while, then slowly creeps up (non paged pool) until it hits up to 20GB (32GB system ram). When I close the tab, it slowly goes down to about 1GB.
Using Bitdefender Total Security Build 18.104.22.168 / Engine-Version 7.87844.
Please tell me if you need more information. As this is a software development workstation, I have quite some debugging tools installed ;)
