Pierre Ossman [Mon, 11 Sep 2023 11:05:25 +0000 (13:05 +0200)]
Completely ignore server clipboard when unfocused

We can get races with clipboard managers in the server that is very
confusing to the user.

When the clipboard changes locally, we tell the server to drop the old
clipboard (as it is now lost). But we don't send over the new clipboard
until we get focus again, in order to not leak more data than necessary.
This causes some clibpoard managers to take over ownership in order to
avoid an empty clipboard. And this takes precedence over the new client
clipboard as it happened later. Effectively reverting the clipboard the
user sees.

Avoid all of this by simply ignoring the server when we don't have
focus. This is likely what users expect anyway as they expect their
currently focused application to control the clipboard, not vncviewer in
the background.
