Windows 10: Why do a white square on my taskbar and a transparent window appear and disappear in a...

It's been a while since I noticed that. But when I start my pc, after some seconds, a weird white square appears in my taskbar in the same time of a transparent window like a application was started and they close at same moment they appears. Like they appears, they disappear instently. I don't know what it is and I really think I should format my computer. Can anyone help me?

Transparent square affecting the mouse

There is a transparent square near the top of my Windows 11 laptop that affects my mouse. It started as two transparent dots, but as I search and try to find fixes, the two dots disappeared, and I was left with the square. Sometimes it completely disables the mouse and I am forced to force shut-down the computer. How do I fix it? Help !!!

Thanks

 

My onscreen keyboard is transparent or completely white Windows 10

When I touch the keyboard on the taskbar, I can see the outline of the keyboard, but the keyboard is completely white. I've tried turning off transparency effects for Wincows. I tried to blindly click where I think the x to close would be. I started the
task manager but it is not listed so that I end it.

It is really annoying when I click a site that normally brings up the keyboard, it brings us this transparent box that I can move around the screen but can't change to get back to normal.

Any suggestions?
