Brief black screen at UAC or wake-up on computers that have two video cards and run Windows 10 Creators Update

Applies to: Windows 10


Consider the following scenario:

  • You have a computer that has two video cards that are supported by the hybrid-graphics technology. For example, the computer has an integrated video card and a stand-alone video card.
  • The computer is running the Windows 10 Creators Update Version 1703 (build 15063).
  • Any of the following actions occur:
    • You're prompted by the User Account Control (UAC) dialog box.
    • The screen saver starts to run, or you close a screen saver.
    • The computer wakes from hibernation (S4).

In this scenario, the screen appears black and the mouse stops working for one or two seconds.


This problem is caused by a code change in the Windows 10 Creators Update. Because of this change, the hibernated video card wakes up when a window station switch occurs.


Microsoft is researching this problem and will post more information in this article when the information becomes available.
