Win10 Quick Assist screen-share shows corrupted desktop

Reported by: Jim Avera Owned by:
Component: other Version: VirtualBox 6.1.4
Keywords: Cc:
Guest type: other Host type: other

Description

If Windows 10 guest shares its screen with a remote user using the built-in "Quick Assist" utility, the other user sees a corrupted screen. Specifically, everything is slanted at a 45 degree angle (see screenshot). It looks like each horizontal row of pixels is offset slightly from the previous one.

HOST: Ubuntu linux 20.04, X-org, Intel graphics GUEST: Windows 10 64-bit

STEPS TO REPRODUCE: In some other Win10 machine (VM or real):

  1. Start the "Quick Assist" app.
  2. Click the "Assist another person" button at the bottom (sign in to a microsoft account if prompted) Note the "Security code" number displayed

In the Vbox VM Win10 guest:

  1. Start "Quick Assist"
  2. Enter the Security code in the "Code from assistant" box

RESULTS: The remote Win10 sees the VM guest's desktop in an unusably skewed form
