Random white flicker on screen

Computer Type: Desktop

GPU: RX 6700 XT

CPU: RYZEN 5 3600 6 CORE 12 THREADS

Motherboard: ASUS ROG STRIX B550-F GAMING

BIOS Version: 1202 (I suppose)

RAM: 16GB CRUCIAL BALLISTIX 3600MHZ CL16

PSU: CORSAIR TX650M 80 PLUS GOLD

Operating System & Version: WINDOWS 10 PRO 20H2

Description of Original Problem: After months of tries, I have finally succeeded in purchasing a 6700 XT from AMD.com. I am very happy with my new GPU, but I have a small problems: sometimes, the screen randomly flickers white, especially while I am playing, but also while I am watching Twitch or YT. I have tried some possible solutions.

Troubleshooting:

  1. I installed the AMD Software and their driver;
  2. Because before the 6700 XT I had a GTX 750 Ti, I have also uninstalled the older drivers;
  3. I fixed the monitor reresh rate, from a strange "59,940 Hz" to a normal "60,000 Hz";
  4. I have also reinstalled the drivers, but nothing happened.

This is not a "real" problem, it happens just a few times in a game session, but it is very annoying. I have a dual monitor setup, and the main one, the one that flickers, is a 27" [4K@60Hz](mailto:4K@60Hz) (Philips 276E8VJSB). What should I do to fix this? Is a graphics card problem or it is related to the monitor? Thank you!
