Teams Helper usually trigger the discrete graphic card on Macs with dual graphic cards. This leads to higher energy consumption.
Could you please stick to the integrated graphic card in all cases?

I have noticed it again, can someone take a look on this? Just launching MS Teams triggers the graphics processor change.
This was solved in the past but seems it sneaked in again.
