Hi, Olive
    Will you please open a new bug in 
    http://bugs.freedesktop.org ?

When you open a new bug, please provide Xorg log and dmesg accroding to
http://intellinuxgraphics.org/how_to_report_bug.html.

Of course please also attach the register dump when using the different resolution?
For example: 1680x1050
             1024x768


Thanks.
