It's really hard to continue doing work when this keeps happening. @appledevs a little help here would be great

Still experiencing this issue and this is not while I'm connected to an external display. It happens when I spin up Docker for work and when I attempt to do something else that requires streaming i.e. pairing on a task via something like Tuple or Slack or even streaming YouTube music.
This has also happened when connected to an external display and/or connected via SideCar to my iPad
