Comparing two pictures with different text returns no diff #117

I'm trying to compare two pictures of a dialog with different titles, but pixelmatch return diff = 0. Am I missing anything? I've tried different values of threshold screenshot createPipelineDialog

I'm not sure how you're using pixelmatch since you didn't provide any details, but it works properly on the images above for me, producing this diff:

Thank you for your response. It seems that I had a bug in my code (I'm using a framework called playwright which makes the code hard to debug) I'm now getting the result as expected.

Thanks!
