So just a few days after I commented that I'll take care of my GPU, I think I offended both fate and lady luck and they returned to bite me. Out of nowhere, weird horizontal lines appeared on the screen. It appeared just few minutes ago. When the lines first appeared the GPU wasn't doing anything particularly demanding, I was working on some Google Docs when the lines gradually appear. Weirdly enough, the lines only cover the top half of the screen, the bottom part is fine. The can be more clearly seen when the monitor is showing bright colours.
Obligatory system specs :
CPU : Ryzen 5 2600
MB : MSI X370 SLI Plus
RAM : T-Force Delta R DDR4 3000 32 GB(16x2)
GPU : Yeston RX 6800 XT
SSD : Samsung PM1725a 1.5 TB
HDD : An old 500 GB Seagate Momentus Thin
PSU : Seasonic S12G Gold
Cooler : Cryorig H7 QL
Monitor : LG 22MP68VQ
I've tried a few things, reinstalling drivers, booting in safe mode, messing around in monitor settings, restarting the PC countless times, trying another HDMI cable (I only have HDMI, unfortunately, so I can't try another port, but I'm open to buying other cables if necessary). Also tried running 3DMark's stress test and it passed just fine (99%). Everything worked fine just few minutes ago.
I've taken some pictures of the problem, but I don't think the pictures are clear enough to show the problem. I'll fetch a different camera and try to take a better picture, will update the post later. But, I wonder what's wrong with my PC?
UPDATE : Pictures
I've uploaded two pictures, one for the top half (with lines) and bottom half (no lines) of the monitor. It's rather hard to see, but it's possible to see the horizontal lines on the top right of the screen on the "problematic" image. Compare that to the "normal" image, where the "pixels" look smoother overall. I've found out that grey is the best background colour to make the lines visible.
