I understand your question.

I am a volunteer reviewer from the Microsoft community, and I am honored to serve you.

According to your description, it seems that the desktop icon becomes smaller when using the computer. There are several possibilities.

The icon has been resized. You may have accidentally modified the size of the desktop icon. Just right-click the desktop, select View, and then resize your icon to three options: small icon, medium icon and large icon.

Change the icon size by right-clicking on the desktop.

The resolution has been revised. You may have recently modified the system resolution, causing the element to display abnormally. You can right-click Desktop-Display Settings-Resolution to adjust to the resolution with the word "Default".

This application does not support large icons. If you are using UWP applications or some programs are useless to adapt to large icons, you may see icons in the middle. You can try to update such programs or contact the developer.

I hope the above content can help you.
