Programs aren't displaying correctly, mostly windowed applications

[bamberr11]

Recently I've been having this strange graphical glitch (for a lack of a better term) with some applications where they won't display properly. I'm not even sure how to describe the issue, but it's often on programs where you highlight a button or text and it glitches it out, displays black squares on top of it or text disappears as shown on the screenshots attached. Games and web browser seem to run no problems, watching videos etc. Is also fine. It ran fine before, and the only thing I can think of that I've changed was plugging in a 2nd monitor but even when having one plugged in the issue persists.

 

I've tried alot of different things from completely disassembling and reassembling the PC, trying a different video card, different monitor, new DP cable, reinstalling literally every driver I can think of, clean windows install, tried both 10 and 11, firmware update on my monitor, swapping the RAM, ran windows memory diagnostic, SFC scan and nothing seems to do the trick - I've ran out of ideas and kindly ask for your help as to what could be the cause of this problem.

 

System specs are

Intel i5 1360KF

Gainward RTX 3080 10gb

32GB Corsair VENGEANCE DDR4 3200MHz (2 x 16GB)

ASUS TUF GAMING Z690-PLUS WIFI D4 MOBO

512GB SOLIDIGM P41+ GEN 4 M.2 NVMe PCIe SSD

Corsair H100x Hydro Series AIO

CORSAIR 850W RMx SERIES PSU

Monitor I'm using is a 240hz IPS MSI MAG274QRX

 

Thanks

is your ram on the vendor list?

Yes, I've just double checked on asus' website. It's a Corsair vengeance kit. If the memory wasn't supported could this issue appear after two weeks of usage but would have been fine beforehand?
