Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

I have the same issue.

I have just installed unreal engine 4 and upon launching it I noticed that every time I move my mouse it causes my screen to go black for about a second or two. At first I thought it was my resolution so I turned it down to 1920x1080 (was at 3840x2160) but the problem persists.

I have no idea what could be causing this issue however I am currently updating my graphics drivers to see if it resolves the issue.

My GPU is a 1070 with driver version 411.70 (I can't roll back because I need the latest drivers for Forza horizon 4).

Edit: after updating to the latest drivers, restarting and changing my resolution to 1080p the screen doesn't flicker as often now, however it still flickers whenever I open and close pop up menus.

I have this issue still! If I place the UE4 Windows on my secondary screen and mouse over anything, the screen blinks black on my HDMI screen, not the secondary monitor. I'm on Windows 7, on a Geforce GTX 980 on Nvidia Driver: 419.35. This issue makes using my primary screen UTTERLY useless on UE4. Please help me. I can not upgrade to Windows 10 for the foreseeable so please god help me.

I think your only recourse is to rollback/install older drivers. There is a hack to disable mouseover prompts, but it will still wonk out from some other actions.
Here is how to rollback drivers:

I can't believe this does not fixed so far. Is this really No.1 engine in the world?

Me too same phenomenon. HDR monitor (LG), newest nvidia driver (419.35), newest Unreal engine.

Please don't say to rollback nvidia driver. This has been months over bug then why Epic games does not acted?

I also have 4k HDR monitor (LG), an nvidia 4xx series driver, and also flashes (UE4 version 4.22), and that's what's interesting, on version 4.12 it does not blink while I work in it. Also waiting for a solution to this problem.

Here is a workaround i found.

Disable tooltips: Navigate to Epic Games\UE_4.20\Engine\Config\ConsoleVariables.ini

Open ConsoleVariables.ini

add the following Slate.AllowToolTips=0

I have this same issue. Only happens for me when I'm using an NVidia graphics card on a HDR monitor that has HDR turned OFF. Turning on HDR in Windows settings solves the problem. Not ideal but may be a workaround for you for now as the constant flickering makes working in UE4 nearly impossible.

I came here with the same problem. When I open the UE Editor and navigate to my "Unreal Project Browser" my screen turns black for some seconds when I hover over any of the menu buttons. I tried to enable my HDR and it seems to work so far. I don't know why exactly this happens. My plan was to watch tutorials on the second monitor (which is not HDR) and work with the engine on my primary monitor.

So if anyone knows why this happens and maybe can explain this to us, it would be very appreciated =)
