weird artifacts on my windows 11 background

[kondamin]

Since it screenshots it's not a vram or ram issue
But it's making me feel pretty uncomfortable

I'm going to try if a reboot fixes it, but it's the second time this happens.

Well if you really is sure for not ram/vram issues...or bad solder points on graphic cards or bad contacts between graphics and PCIe slot. Try cable between monitor and graphics, put out and then in from both sides or change with other cable if you have. Looks in your DP or HDMI ports (what you use) for any damages.

i restarted and the issue is gone.

if it were a hardware issue other than maybe something going wrong with my storage corrupting that image I would not be able to screen shot it is my thinking

Ummm, I think your way of thinking is only partially correct. I think the screen shot only proves your monitor is not the problem.

Sadly, you told us absolutely nothing about the hardware. We don't even know if this is a PC or laptop.

If me, and a PC, I would swap in a different graphics card (or switch to integrated, if supported) and see what happens.

If a laptop, you could connect an external monitor. If the artifacts appear there too, then again, that proves the laptops monitor is fine.

well the problem is gone with a reboot, can't do much testing with different graphics cards and and other hardware if it's an intermittent issue.
memory is running well below spec and the gpu isn't anywhere near stressed practically ever.
Also weird it's just the wallpaper not the programs on top.

I don't have new graphics card money.

And yes you are correct, a screenshot is pulled from the frame buffer in vram

Agreed. Intermittent problems you cannot duplicate on demand are the hardest to troubleshoot.

All I can suggest now is to inspect the interior to make sure it is clean of heat trapping dust and that all fans spin freely. Then, while in there, double check to make sure all data and power cables are securely fastened and the card and RAM are inserted completely.

Do you have a chipset issue? That's the only thing that comes to mind where this kind of behavior could exist.
That shouldn't happen. Ever.

Only on the wallpaper, you said? Here's my suspicion: data becomes corrupted during transcoding from the original picture to the one that Windows keeps in its temporary storage location. In Windows 10 and 11, it's C:\Users\<user>\AppData\Roaming\Microsoft\Windows\Themes\TranscodedWallpaper, or perhaps "Local" instead of "Roaming". It's a JPEG file but without any extension. If it happens again, find the file, copy it somewhere else, add the .jpg extension and open it to see if it has artifacts. Unfortunately I don't know where the originals are stored, some are in C:\Windows\Web but in my case (Win 11 and Microsoft's app that changes wallpapers every day), they aren't.

The transcoding (probably just resizing for your screen) may be triggered on every reboot, which would explain why it solves the issue. Choosing a different wallpaper would solve it too.

But file corruptions don't happen for no reason. Testing the system RAM would be in order.

Did this issue ever pop back up for you?

I'm having an extreamly similar issue to you & the artifacts look the same. Mainly is occurring on the Desktop but will occasionally occur within other windows.

Stress tested GPU, tested the ram, even did a full windows wipe & reinstall. Happens on both monitors.

Restarts will "fix" it for a random amount of time.

I haven’t seen it happen again since posting.
Mind you I did under clock my 3090 quite a bit after this started happening.

I did a system refresh on Sunday so the under lock should be gone, I will report back if it starts happening again.

I have had something similar for a while. If I switch between inputs on the monitor or turn it off and on, then it's fixed immediately. Pretty sure it's HDMI handshake issues or something similar.
I guess I could have tried with other cables, but it's so fast to fix that it doesn't bother me.
