We don’t at the moment differentiate, but it is definitely a feature on the roadmap. There are multiple ways to solve this and we are considering quite some of them:

1. Grayscaling browser before screenshot 2. Using custom diffing engines that enable for ignoring regions like odiff 3. Trying to be smart and analyzing images with machine learning to identify how meaningful the difference is (moonshot but worth exploring)

Our approach to this in general is that if false positive like this happens we can just batch approve all the differences and be ok with that as it was a subtle rendering change not dependent on us or our direct third party dependencies.
