[FreeRDP-devel] 回复： 回复： 回复： mouse cursor jumping

[Zihao J. <zih...@ya...>]

Hi Petr,
The 'skipping back' problem could always be reproduced in poor network environment. Could you help to open an issue to track it?We can have enhancement that the server should not send back the mouse position to the client where user is moving the cursor. I think the idea to update the mouse position to clients is to notify the clients which are just 'observers'. In multi-client scenario, usually there should be only one 'operator' who is move the mouse or click it. We only need to update the mouse position to the 'observers'.
ThanksZihao

 Isn't there a way to identify movement which come outside of FreeRDP 
client and for such call x11_shadow_pointer_position_update?
