Windows 11 high CPU usage on window resizing

I opened Task Manager. When I put the mouse in its window’s border and resize the window rapidly, make it bigger then make it smaller and doing this continuously for a few seconds, strangely CPU usage goes higher than 20 percent. if I stop resizing, CPU usage come back to normal.
I have a Thinkbook 14 Gen2 itl with 16G Ram and corei7-1165g7 as cpu and MX450 as GPU
Why this simple task is CPU hungry?
see my screenshot:

Edit1 :
I repeated this action in a windows 7 system and CPU usage remained 0% ! so I think something is wrong with windows 11.
