I’ve had this issue as well on June 10th. After reverting the Nvidia Game Ready driver to the previous version (as it was at the moment), the issue was fixed. With the newest driver version, UEFN doesn’t flicker. (One other game had a similar issue with the brightness being too high, fixed with reverting the driver as well. Because of that, my assumption is that it’s not UEFN’s fault.)
GPU - NVIDIA GeForce RTX 5060 Laptop GPU
Two screenshots, one capturing the editor at the highest brightness, the other one is how it’s usually.
