How to fix this problem when marking app shortcuts on home screen, Windows 10, PC?

If you drag the mouse on the start app screen of my HP laptop with Windows 10, this normally blue-transparent field, with which you can mark the app icons, for example, has recently appeared to me completely instead of a blue-transparent field transparent field with white dotted frame that also bends around a bit. This problem does not exist in the file explorer.

This is not a particularly big problem now, because marking it, etc. Yes, it works the same as before, but it is very annoying and gives me a bad feeling, since my laptop is also quite new.

I quickly ask for tips to solve the problem!

It is best to reinstall the laptop if it does not work properly

Either you reinstall it from a USB stick or from a boot CD

First of all, I would back up your data and reset the entire PC once before you reinstall it
