Not sure how to get this to work. Everything except Chrome and also Discord, do not generate thumbnails in the open tasks.

Some windows (such as the windows that docks, etc, are made of) are called 'layered windows' because they are rendered off-screen by the application and the resulting bitmap is then composed into the screen by the Windows DWM.

Previously to Windows 10 you had unrestricted access to this memory bitmap even when it belonged to another process. Unfortunately it seems that Microsoft at some point decided this could be a security risk (sigh! NO IDEA why since the same image will be displayed on the screen) and blocked access to this bitmap.

As such, applications that use layered windows to compose their contents (and possibly even applications that use DX surfaces) can no longer have an iconic thumbnail generated for them by the Winstep application. Hovering over the icon will still display the 'live preview thumbnail', however, since this is generated by the DWM itself.
