After uploading images some websites will display scanlines instead of images. This happens to some tab icons as well.

I see other people are having the same issue, but nobody seems to know the answer.

This can happen if you have "Resist Fingerprinting" enabled and block canvas.

Do you have enabled "Resist Fingerprinting", i.e. is this pref true on the about:config page ?
