Black circle on images in PDF viewer
Hi, I have noticed images in some PDFs do not render correctly - they have a black circle in the top left corner of images. I have seen this in the Firefox PDF reader too. No idea if there is a fix, I read that it has to do with hardware acceleration so maybe this can be disabled?
layers.acceleration.disabledto true — i.e., disabling hardware acceleration — will almost certainly fix this in the meantime if you're experiencing it, though note that graphics performance will be slower.)
