Good news: I have found a solution to enable us to calibrate stylus with user-defined grid when Wacom feel driver has installed on your surface pro.
The trick is to edit the registry and no risk at all if you do it properly. Most of surface pro users experience LinearityData error when run the script:
tabcal lincal novalidate XGridPts=0,30,50,150,350,650,945,1240,1540,1740,1840,1890,1919 YGridPts=0,30,50,150,350,630,830,1030,1050,1079.
Note that delete 'devicekind=pen' in the script(the script above is an example) does not solve the problem most of the time.
The solution is to delete the [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&0002\Device Parameters], [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TabletPC\LinearityData] and [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TabletPC\UserLinearityData] using your registry editor.
Note that the id "VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&0002" of the first key's name could be different on your device. A search in registry for LinearityData is suffice to find it.
Then you are able to run the 'tabcal lincal novalidate XGridPts=0,30,50,150,350,650,945,1240,1540,1740,1840,1890,1919 YGridPts=0,30,50,150,350,630,830,1030,1050,1079' script.
In this step, the values in [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&0002\Device Parameters], [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TabletPC\LinearityData] and [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&0002\Device Parameters] are updated.
Bingo! You get the same accuracy in the corners as the one without Wacom driver.
To backup the linearityData, use the registry editor to export these three folders(the first one is the most important). You can recovery to this profile whenever you want. Is that nice?
Now you can also calibrate your pen using the default 4 points calibration tool in control panel. It will add a secondary correction, which is good in some cases. And the corner accuracy will not be jeopardized by this 4 points calibration. The data file of this 4 points calibration seems to be "C:\Users\[your user name]\AppData\Roaming\WTablet\ISD_Tablet.dat Backup this file is also recommended.
Enjoy!
