Windows 10: Desktop Wallpaper glitchy - Funny texture overlay

Hello! First time here.

I've begun experiencing odd behaviour and I haven't personally seen this before in a windows computer.
I've seen various screen bugs before but, this one's a little different and it just screams to me that it's an issue with Windows 10.

This only started happening recently.
I have not updated any of my drivers because it shouldn't be of much concern this is the only visual glitch I've been experiencing since owning this laptop(nearing 3 years now, originally was windows 8):
Acer V3-772G
Windows 10
16GB DDR3 Memory
Intel Core i7-4702MQ @ 2.20GHz
Nvidia GeForce GT 750M

The problem itself isn't urgent and is simple but odd in nature.
It's purely the desktop wallpaper experiencing issues. None of my icons are affected by it.
Originally this funny metal 'texture' would appear over my screen only on boot and log in(it's not all the time but very often) and it'd remove itself as I highlight things (so I would have to highlight the entire screen to remove this funny 'texture' completely off my wallpaper) hovering over to pre-highlight an icon would also remove this texture from around and in behind my desktop icons.

I ignored this until just then it happened mid session while I was on playing a game (may have been there for a few minutes unsure, as I'm fullscreen on my game etc.)
And despite highlighting things and moving my mouse around, it would not remove itself.
I fear the worst expecting to have to restart, but as I predicted, changing wallpaper got rid of the visual bug to my wallpaper, then changing it back to my wallpaper I normally used was fine.

Thanks for taking the time to read my odd issue, bit hard to search for problems like this as it's rather specific and there's always a lot of display issues. I've just never heard of one like this before. Hence my reasoning behind suggesting it's a OS issue with Windows 10.

Thanks again,
.


Images for reference:
(excuse me hiding all my icons, figured i'd just do it as it's not the focus regardless.)
One picture is when it happened just then and I couldn't get rid of the funny texture, note my wallpaper is visible at the very top however. Changing the wallpaper to something else then back resolved it though, unlike normal where on boot I can just highlight the entire screen and it'd fix itself. Included an image of what my wallpaper normally looks like.

Dark Blue Desktop Background with small white dots, can anyone explain this?

Black screen with white dots overlaying my desktop background happened to me after last Windows 10 update. All my icons were still there just the background was hidden behind the overlay.

Thank you zachd for the hint to check wallpaper settings. For some reason they were reset to slide show and tile by the update. Very Strange!

 

My desktop wallpaper changes itself with unknown pictures.

(Sorry for my english)

Hello, at Janaury I had a very strange experience: my desktop changed wallpaper and color of theme, for background there were pictures of the emoji unicorn put beside like a texture. It was strange because that picture was not saved on the pc, was not downloaded...

I changed the desktop again and I ran a scan with Malware bites, I only found a suspected directory that I deleted.

So, I had no problems until yesterday.

The desktop changed again itself with a picture took from a blog I think. I'll post a photo.

It may seem funny because that wallpaper is ridicolous , well it isn't funny for me. I had not that pictures on pc, I use flat colors as desktop wallpaper. I ran a scan again, and the scan with AVG and Malware bytes: no malwares. But the scan were too fast.
Could the antiviruses have been hacked?

And if I have "someone" in the pc?

(I have an HP from 2014 with i3 but I can't check the type now)

I created a new user without using internet connection, changed password, set new user as admin but I could not enter in the "old" user directory for save my files in the new user.

I'm very worried. Please help.
