    This has been an intermittent problem for me since switching to Parallels for Apple Silicon.
    Sometimes after a Windows 11 update, the display for some apps is corrupt or black.
    It usually affects Microsoft Edge and the Terminal App:

    Removing Parallels tools fixes the display for these apps, reinstalling it corrupts the display.
    Any suggestions?

    Well, I figured it out myself with the help of Perplexity.
    First, I turned on Software Rendering (WARP) in Terminal which fixed the black screen:

    That made me realize that it is a graphics rendering issue.

    Then I ran this:
    sfc /scannow
    Which reported some of the graphics drivers were corrupt and it repaired them.
    Now all of the Edge, Chrome and Terminal pages render correctly.
