Windows 10: Blank White Square in the Middle of My Screen – How to Fix It?

Hi everyone,I'm experiencing an issue where a blank white square appears in the middle of my screen while using Windows 10. It doesn't go away even after restarting my laptop, and it seems to overlay on top of all applications. I've tried updating my graphics drivers and running a malware scan, but the issue persists.Could this be related to a system process or a background application causing conflicts? Has anyone else faced this problem, and what are the possible solutions?Additionally, I recently had a water spill on my laptop and got it repaired. Could this issue be related to hardware dam

:)

Small white square on screen

I have recently noticed a small white square on the bottom right of my laptop screen. I have absolutely no idea what that is or how to take it off. Here is a print screen.





This little white square is not on the top of everything on the screen. If, say, I click on the notifications button, we do not see the square





Any idea of what that is? Or how to get rid of it?

If it is relevant, on the tray I have:

• CCleaner
  
• Acer Care Center
  
• GeForce 920M
  
• Avast
  
• NVidia GeForce Experience
  
• Avast SecureLine
  
• Drive File Stream
  

My computer is an Acer Aspire E15 with Windows 10, 64 bits.
