Description of the issue:
Brave for Linux is extremely sluggish especially after I join Google Meet, where I share screen, etc. There are some websites which also trigger this problem. But I believe the main slowdown is seen when I start Slack app.
This sluggishness is also translated into Slack app, which used Brave core. I often have to wait 3-5 seconds to change a channel. Lag is apparent when typing.
The sluggishness shows when moving tabs, detaching tabs, clicking on refresh button, etc. Everythink has got a 1-2 seconds lag.
The issue is not related to CPU or RAM (32GiB) resources. I have more than enough of both. I see utilization about 5GiB of memory and 6-10% of CPU when running Google Meet.
Steps to Reproduce (add as many as necessary):
Just using the Browser is enough. Starting Slack app or Google Meet increases the lag.
Reproduces how often:
Every time I use my laptop. Especially when running Google Meet, Slack, etc.
Expectations:
How can I troubleshoot this issue and collect logs which can help developers to fix this issue.
