There is no problem in functional use. I noticed this situation a long time ago: in some versions, the function icon will be windowed with the application, but more often, this will not happen in the updated version, but the application is windowed but the function icon is still in the initial position and will not change with the movement of the application. Haha, in fact, I like this function icon that follows the application window, which is convenient for opening the same functions needed for application management.
