Screen glitch
Hello!
I recently moved overseas with my PC, and it was working perfectly before the move.
After arriving, I bought an ASUS ROG Strix XG27ACS (27", QHD, IPS, 180Hz) monitor. Since connecting it, I've been experiencing random screen/GPU glitches.
Here's a video showing the issue:

I sent the monitor back to the retailer, but they tested it and couldn't reproduce the problem.
The glitching seems to come and go—sometimes it's barely noticeable, and other times it's much worse. It happens everywhere, even on the Windows desktop, and it's most noticeable on dark backgrounds.
My system:
- GPU: EVGA GeForce RTX 3080 FTW3 Ultra
- PC: ASUS ROG Strix G35 (Ryzen 7, 32GB RAM, RTX 3080)
- PSU: Replaced the original stock power supply with a Corsair RM1000x.
My GPU is mounted vertically, so I'm using a PCIe riser/extender cable. This setup worked perfectly with my previous monitor back home, a Samsung Odyssey G5 S27CG510 (165Hz).
Does anyone have any ideas where I should start troubleshooting? Could this be a monitor compatibility issue, a DisplayPort cable problem, the riser cable, or something else?
The PC worked flawlessly before I moved, so I'm wondering if something may have shifted during transport or if the new monitor has exposed an issue that wasn't noticeable before.
Any suggestions would be greatly appreciated!
