Your image is rendered slightly differently on the different OS's.&nbsp; This&nbsp;is fairly common in automation.&nbsp; You may need to use separate baseline files for each OS.

Either that or look at changing the tolerance level in your image comparisons.

artems · Answer

Hello gentlemen,As far as I can judge from the attached images, the dissimilarities are most probably caused by various font smoothing settings under different OS's.Therefore you may perform any of the following:    a) Disable or set the same font smoothing method when both the baseline and actual images are captured.    b) Use separate baseline files for each OS as Russell suggested.    c) Tune the comparison tolerance as Robert suggested.&nbsp; Namely, adjust the value of the PixelTolerance&nbsp; parameter. See the "Ignoring a slight difference between images" section of the "Comparing and Finding Images - Specific Tasks" topic for details.
