VidModeSwitchTo Question

Hi all,

I'm debugging X server and find when client request a VidModeSwitchTo,
the CRTC is updated with a new mode but the server ScreenRec.width&height
are not updated with the new mode and server also send a RRScreenChangeNotify
with the old value. Is it the X server bug or the expected VidModeSwitchTo behavior?

My server is 1.11.4 under Ubuntu 12.04. Either Radeon and AMD driver can duplicate
this problem.
