coordinates off by about 15-20 pixels, on windows 8 surface pro 2

[saosaok 0]

The bot worked fine on my windows 7 64 bit desktop. I was trying now on my Microsoft surface pro 2 tablet running windows 8.1 64 bit. The bot starts fine. however, all the relative window coordinates are off by 15 pixels on y, and around 5 pixels on x. 

 

Do you know how should I resolve this ? 

 

Is there a global offset that I can apply ? or I have to go into the coordinates.ini and manually adjust all the coordinates. 

 

 

I know the coordinates are off after debugging it with AHK's window info script. 

 

 

 

Thanks

update, I got it resolved. 

 

My assumption was correct. It has something to do with the tablet display pixel upscaling. 

 

I need to Disable display scaling on high DPI settings.

after that it worked ok.
