Thanks for letting us know!
The false positive feature should filter out exact matches of comparisons.
Do the comparisons you marked as False Positive show the same differences, or slightly different ones?

Thanks, @steffenbew.
The change is always 4 pixels, in the exact same location as far as I can tell.

Hi @asafm7,
I looked at your screenshots in our database. The way we save the false positive is via a checksum of the diff image. That means not only that the differences need to be at exactly the same spot, but also that the rest of the image must not differ.
At least if you compare the screenshots from 05/29 and 06/16 to 06/19 and 06/19, you will see that at the bottom of the screenshot there is a small horizontal rule at the beginning of the footer.
For the other one, I cannot make out a visual difference but the checksum from the comparison is definitely different. I can also see in our DB that there are a few comparisons marked as false positives and some alert were filtered out. It just also seems that from time to time the checksum changes.
So from our side, the feature is working as expected. But we will keep your case in mind and see if we, in the future, make some changes to how a false positive is identified.
