Hi Mikael Puusaari,
By any chance are you sorting by name to avoid the processes to move around while looking at them? if so holding down the CTRL key will pause refresh and allow interaction with the interface and processes.
In Windows 11 in the details view, once you order your view by a collum and close and reopen task manager the previous setting should still be there, setting it by default however is currently not supported as far as I know.
