Thread:Project:Support desk/PNG Images Displaying Slightly Larger, and Blurry?

I have a series of PNGs that are sizing wrong, blowing up each image slightly. (We are running MediaWiki, recently updated, sorry I don't know the exact versions).

It's really weird, and makes all the text in the images just a LITTLE bit blurry. (I thought it was sizing off the transparent shadow or something, but I tested that.)

I will try to enclose the before and "while viewing screenshot".

Any recommendations, or is this just a bug in the way MediaWiki displays images?
