Thanks for the report. The file size has always been larger but the blur is too high and it used to be lower in 1.12.1. We'll fix it for the next release.

This should be fixed now. The zip you mentioned will only be fixed for jQuery UI 1.14.2 or newer, but the Download Builder now builds correct sprites even for older releases, so you can just go to https://jqueryui.com/download/, choose everything and click Download to get a fixed version.
