Unreal Engine 4.23 screen flicker

I have started to use Unreal Engine for hobby and learn c++. The problem is that the screen begins to flicker in UE while i'm works. If I run other programs or applications the screen don't flicker, only flickers in UE. I updated the Intel drivers and Nvidia drivers (1050Ti) but the problem is still unsolved. Thx.

Solution

Have you tried to manage your graphic card in the NVIDIA Control Panel ? I think that customize your settings for Unreal Engine can fix the problem, I had the same issue and it's working for me.

I don't even know why, but Unreal encounters some issues when he has to deal with different graphics cards in a same time. So, you have to set manually the graphic card for use in order to avoid conflict and flickering.

Open your NVIDIA Control Panel
In the panel Manage 3D Setting, choose Program Setting.
In the part Select a program to customize : search for Unreal Engine editor(UE4Editor).
In the part Select the preferred graphic processor.....: choose High-Performance NVIDIA Processor
Click on apply, & that's all. Reopen Unreal Engine and see if it's working.

Here a screenshot of the settings that you should have.
