It might just be the browser but the text is impossible to read on most pages. The background, while lovely, washes out the text. It also interrupts the flow. I'd suggest switching all instances to a simple colored (even if that color is white) background for readability.
The background is white for me on Chrome, MSIE and Firefox on Mac and on Windows (looks OK in Chrome on Android, too), what are you using?
One caveat - if you're using an obsolete browser (ie, MSIE 8) you might be out of luck...
