What’s worse, the list of tasks/apps in Task Manager for some reason populates gradually over a couple of seconds, so when you right-click on some task to perform an action, it might switch to a different task under the mouse cursor while you’re clicking because it’s still populating.
For me at least "details" tab populates in one step (there is a slight delay and then all processes appear). You can set it as the default tab as it's the most useful anyway.
Holding the control key down stops the task list from updating. Release the key to resume updates. Works on Windows 10 and 11.
