Hey everyone, there are a lot of people that experience this issue.

If your Unreal Engine editor menus or screen go black - blank - or flash continously and you have to restart unreal engine. (You probably have an NVIDIA GPU) try this registry fix and restart your computer to fix it. I did it on my pc and it works.

I had this same issue and was able to fix it by disabling MFAA through the NVIDIA control panel. Credit goes to this Reddit post. I’d try that before installing anything.

I also have encountered this issue.

I’m running a fresh installation of Windows 11 with an Nvidia 4070 graphics card, as well as Unreal Engine versions 5.1 and 5.2.

I have two 2K screens, and the main screen in Unreal Engine frequently goes black. I can temporarily bring it back by pressing Alt+Tab, but as soon as I switch back to Unreal Engine, the screen flickers and goes black again.

I attempted the solution mentioned in the Nvidia support article by modifying the registry, but unfortunately, it didn’t resolve the issue. Here is the link to the article: After updating to NVIDIA Game Ready Driver 461.09 or newer, some desktop apps may flicker or stutter when resizing the window on some PC configurations | NVIDIA

Although the latest Nvidia driver download claims to have fixed the black screen or flickering problem, I am still experiencing this issue.

Tomorrow, I plan to try installing previous versions of the Nvidia drivers to see if that resolves the problem.

In my case, I had the same issue with the black screen, but interestingly, for the last five days, I haven’t encountered it at all. I noticed that both of my 2K screens were connected with a cable that had HDMI on one end and something else on the other. I replaced that cable with a standard HDMI to HDMI cable, and since then, I haven’t experienced any black screens
