During mouseover the screen flickers, goes to black and texts are distorted / extremely enlarged.  
Working not possible.It happens in new and old projects.  
Using an Intel I9 with 64 GB Ram and 2x Quadro RTX 8000 with latest drivers.  
Any ideas?

Same problem, it’s really annoying. Only solution so far is to reload editor

hi guys,

the reason is Nvidia Geforce Driver Update . you have to go back to Nov 2020 version your Nvidia drivers.

I solved it going back to Nvidia drivers Nov 2020; and there is another Bug Report on this and see this is only the solution unless Unreal changes their implementation;

Here is the link to other report and you will detailed solutions;

The bugfix in this video did the trick for me: [UE4 Editor Flickering Fix - Bugfix - Unreal Engine Version 26.1 - YouTube](https://youtu.be/71kc3qP3mF0)  
You need just to rollback your nvidia drivers.
