Windows 10: Mouse randomly shows on screen, causing in-game camera to stop until I move it back to middle.

So I play lots of java edition.And one issue that sometimes springs up, is when I swipe my mouse right fast, the mouse will temporarily exit the screen, but will still hit the Fullscreen border of Minecraft.This makes it harder to pvp, and I believe it's a windows issue from what I have heard, people say to use a third party app to fix it, but I do not trust most third party apps which claim to fix those sorts of things.People also recommend registry changes, but everything in my registry is identical to after they make the change, but I didn't at all.Any help would be appreciated very much wi

Black rectangle shows up middle of screen- mouse doesnt work within it

For months now I have been getting a black rectangle in the middle of my screen. Sometimes, depending on the window that's up, it doesn't show as anything - it's transparent, but it's still there. On other windows, it shows up as a rectangular hole in the window that you can see through to the desktop. Regardless of how it manifests, the mouse has no effect within the rectangle. I have to reboot for it to go away. It never goes away on its own. I do some gaming and thought it was related to opening Steam and the game - either PUBG or Ring of Elysium, but it's not. It happened today after a restart and I hadn't done any gaming. I just can't pin it to any activity I perform on the PC. I'll post pictures.
TIA!

Since my last post, the box has reappeared but Photos was not in the list. Today, I closed one of two entries called "system" and it went away. Btw, fwiw, Winlister mentions several programs are open that arent open and havent been opened since last reboot, like calculator.

 

Mouse pointer randomly stops


For quite awhile, I've been encountering a mouse pointer problem on my PC (Windows 10), and its driving me nuts *Mad because it never happened while I was on Windows 7.

The cursor occassionally or randomly stops moving when I move the mouse consistently.

In the demonstration, I moved my mouse consistently towards right, but cursor stops moving at few instances while my mouse is still moving. To put this into what it feels like, it feels like something is pulling or stopping the cursor randomly, if cursor is stuck, it won't move if I move the mouse less than 2mm in all directions but it will move if I move the mouse greater than 2mm in all directions. Sometimes it happens more often and sometimes it happens less.

My mouse is Logitech G502, I believe my mouse has no problem because I tried it with my laptop (Same OS and Mouse driver) and it worked perfectly fine.

My mouse driver don't need update. (HID-compliant mouse, 10.0.10586.0)
My GPU driver don't need update. (NVIDIA, 10.18.13.6519)
I don't have Logitech Gaming Software installed.
I tried different USB ports (2.0 or 3.0) and it makes no difference.
The problem still happens in safe mode.
Reinstalling Windows shall be my last resort.

Any suggestions?
