Windows 10: Why am I getting weird artifacting visual bugs when I change Windows security settings?

Build: https://pcpartpicker.com/list/CfHsGLSometimes, I get a weird artifacting visual bugt when I change my Windows 10 security settings. My PC freezes up for a second and then a line of something that looks like a QR code. It's all black and white. It looks staticky. Is this an issue? It only started happening fairly recently. It's worth noting that I'm getting a 0x80070643 error when I try to download tthe 2024-01 Security Updatre for WIndows 10 KB5034441. Is this related to that error, and how do i fix that error too? Thanks!

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Step-by step overclocking in Wattman

Why am I getting this strange visual artifact with Windows 10 menus?

- suggests a link with fast startup perhaps?

Worth running the troubleshooter at least, and the you have the other options to play with.

- only thing I can think of bar research is a process of elimination- which from your description would be slow and painful.

There's a sort of interesting suggestion in post #10 here:
Start Menu Corrupted - ms-resource:appDisplayName Solved - Windows 10 Forums

Have you checked your disk and RAM? As it happens over a long period, could there be some sort of degradation?

 

Anybody know what these artifacts are?

Sorry, was off for a while...

I finally found the Unicode setting. Thunderbird settings are convoluted, at best.

First, here is the Unicode setting.





Second, the font. Notice it defaults to Arial. I had gone back and changed mine to Calibri from Segoe. This setting is a bit tricky to get to. Mouse likes to jump off focus getting to it. You need to click Options to get a list that includes Options. *Confused Weird.

Hope this helps......
