Describe the bug
When outputting text in color in a PowerShel window, the entire image starts to flicker. Here a Chocolatey update was executed for all installed applications. As soon as the PowerShell window is minimized, the rendering of the desktop is possible again without errors. Apparently only certain output in PowerShell is responsible for the problem.

To Reproduce
Steps to reproduce the behavior, like:

Connected to Dell Latitude Laptop with Windows 10
Open a PowerShell Window and update all Applications with Chocolatey "choco update all -y"
Now the rendering has problems with the powershell output

Expected behavior
A clear and concise description of what you expected to happen.
