Have you enablled the in_place_optimize_for_browser filter? I found this [#1489](https://github.com/apache/incubator-pagespeed-ngx/issues/1489), maybe unrelated. Sounds like some related with user agent. If so you can try https://mysite.com/?PageSpeedFilters=-in_place_optimize_for_browser At this point you can make some experiment: 1.- Whats happens if you disallow this file? (ModPagespeedDisallow wildcard_spec) 2.-Whats happens if you put an uncacheable http header for this file? (cache-control: private) 3.- What if put a @font-face? (in the images you posted I can“t see **@font-face**{ font-family:.....} so maybe rewrite_css will take this as a "normal" css and in these snippet "black" is a color, not the name of any thing) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
