Zoom uses absurd amount of memory and CPU

[gvicente]

I've been having this problem for months, but today I upgraded to version 6.2.3 (Linux, Ubuntu) and it got much worse. I was recording a Zoom meeting and I noticed lag when writing on the whiteboard. I opened `htop` and saw that Zoom was using the CPU at almost 100%, ALL the memory (that's 24 GB) and also all swap memory (2 GB). I was forced to kill Zoom and restart it. This makes Zoom practically unusable.
