Bug Description

On nouveau in clone mode the hardware cursor lags a lot (by seconds) if a client is rendering constantly.

Hacking the server to force use of the software cursor however fixes the problem and it becomes perfectly responsive.

At a guess, it would appear moving the hardware cursor on nouveau is synchronous. At least much more synchronous than it is on intel with the same displays connected.

summary: - Clone mode on nouveau is super-laggy (mouse lags several seconds)
+ On nouveau in clone mode the hardware cursor lags a lot (by seconds)
