What happens to a flow when a user clicks on the "X" button on the form?

I have a flow that shows an "in session" form. When we click on "Submit" or "Cancel" button, we take further steps and eventually complete the flow. For user there is also an option to click on "X" button in top right corner or they can close browser window. 

What happens to flow instance that was initiated? What is the impact on overall server if we have hundreds of thousands of "in session" form closed using "X" button

When an in-session form is closed using the 'X' button, the Form is considered to be complete and the Flow terminates. Closing Forms in this way will not affect the performance of the server as the Flows will be in a completed state not under a running state. 

Additionally, If we want to prohibit the user from using the 'X' button, we can enable the 'Hide Title Bar' property found under Properties→Form Setup→Sub Dialog of the Form step in the Flow designer.
