I also agree that any message to allow/prevent background transparency may
be strange for common users.

These are some of the situations in which I think it may be problematic to
allow background transparency (In which it shows your own desktop and not
other web pages):

If a 100% transparent background is used in full screen without any element
could confuse the user  preventing the user to do anything until they
realize its a webpage (however, usually the browser ask you if you want to
open that page in full screen mode).

An error message (simulating the OS) could be presented to the user in many
fake situations. However, even without transparency it is possible to create
fake alert messages (so I'm not sure if this is a valid case).

Could someone comment other cases in which it may present a security risk or
problem of using background transparency? (It could help to show if a
message or setting should be specify for this matter).
