How to solve the gap in the middle of Win8.1 taskbar icon

During the use of a Windows 8.1 computer, some users found such a problem. The application icon on the taskbar does not know why there is a gap in the middle, and the gap is still large, as shown below. This phenomenon is quite strange, how to solve it?

Solution

First, do you want to determine whether the three icons on the right side are fixed to the taskbar? If it is fixed, please lift it. Lock, then restart the system, do not run the program corresponding to these three icons, wait an hour or two, and then run another program.

This program can't be fixed to the taskbar. The purpose is to display a new button on the taskbar, and then see if there is such a big gap between the new button and the previous icon.

Finally, if the icon of this program appears in the normal position of the taskbar, then basically the problem can be solved. You can launch these three applications again, and try to see if the icons have such a large gap on the taskbar.
