What looked like a rendering bug turned out to be a clever JPEG decoding optimization in Chrome.

This icon looks better on my colleague’s computer

A while back, when chatting with a colleague over their computer, I noticed that a logo did not look exactly the same as it did on mine. It looked thinner on theirs and more faithful to the original image. It was rendered at 15px; here is an upscaled version.

Note: this was not the original image. It happened a while ago, so I made a new image to demonstrate the issue.

On the left, Firefox; on the right, Chrome.

If you squint, or take a step back, the one from Chrome looks thicker. A bit weird, but swapping the image for an SVG fixed it.…
