Description

This issue seems to be occurring on a variety of Nvidia cards. So far, I haven't seen any indication that it is affecting AMD graphics cards. The majority of the reports have indicating that the problem appears when working in Blueprints for an extended period of time. It seems that rolling back to Nvidia driver 460.89 fixes the issue. Also, restarting the editor resolves the issue as well.

Steps to Reproduce
  1. Upgrade your Nvidia drivers to the latest Game Ready or Studio version
  2. Use the editor, especially blueprint scripting for 10 minutes to 2 hours

RESULT:

The editor menus start flickering and turn black or disappear entirely.

EXPECTED:

The editor UI doesn't experience graphical glitches with extended use.
