I have been using Brave for a few months now. But for the last few days I have suddenly had my fan going at full blast when Brave is running. Checking activity monitor it is clear that it is a Brave Helper process that is pegging CPU at 100%!!!
I think this started when I was having a call via Jitsi.
I love Brave, so I am truly hoping there is a solution to this problem (looks like it has been around for a while in Google searches).
