zoom causing kernel_task to spike - cpu usage off the chart

I was able to resolve this issue just by unplugging from my extra monitor - went back to normal. As soon as I plug it back in, it spikes again

Appears to be a compatibility issue with the Zoom app running on macOS Big Sur. Have you contacted the Zoom developers yet to see if they have a solution or updated version of their app specifically for you version of macOS?
