PixelChecksum - different sum each time for same unchanged region

Recommended Posts


This is my code:

#include <ImageSearch.au3>
Local $x3, $y3
 $result4 = _ImageSearch("icoc/N.png", 1, $x3, $y3, 60) ;Finds N letter on minimap in game
 $checksum = PixelChecksum($x3+5, $x3-5, $x3+60, $y3+8) ;checks pixel amount in the region near N letter (ingame)
 $checksum2 = PixelChecksum($x3-1000, $x3, $x3-950, $y3)  ;checks pixel amount in the region somewhere outside game

The problem is $checksum is always different (huge differences in reported amount each time). What's more selected region is game user interface so I don't think some pixels are changing. $checksum2 is working correctly (region outside game for example browser or desktop) - reports always same check sum for unchanged area.

Anybody has idea what can be reason of this and solution for it?
