[PATCH 0/1] MR4676: server: Check whether the cursor has been set for a thread input.

[Rémi Bernon (＠rbernon)]

We are preferring the thread input cursor over the global desktop
cursor, but if the thread input has no cursor yet, for instance when
thread is attached to another thread without a message queue yet,
it will end up being invisible.
