Windows 10: Anyone know how to fix this screen annoyance?

This started happening when I opened up the Xbox game store app about 2 weeks ago, as I was scrolling through the games the pictures would get grainier and granier until they were very distorted and black and white but everytime I'd click on one it would go back to normal for a while. I just figured it was temporary and it is but it is still annoying when it starts glazing over and I can barely see what I'm clicking on. This screenshot is when it happened again more recently, I had Opera GX, Figma UX Design Application, File Explorer, and a live Zoom meeting going, and the screen would star

@smoka Great you fixed it and would be interesting to know how you did it. Care to list the basic steps you took to do it so that it can help others stuck in the same situation?

 

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)

Screen size does not fix.

Since the new upgrades the screen size is too big for my 7 YR old Toshiba Laptop, which I use constantly. I Can not access the x or the scroll bar. The character's are Hugh, stretched and distorted. I have followed every single step listed in troubleshooting
and even paid two computer techs to fix it. NOTHING WORKS! There used to be a simple one step adjustment: Settings: Display: Screen Size. Neither, Resetting, troubleshooting app, driver updates, changing to another resolution (which btw is suggested as a
fix but non existant) nothing works. I am at wits end. The last guy I paid to fix it suggested I just buy anew unit? I can't afford that. Please please address this issue asap. Thank you
