8 years ago Did you update paper-icon-button without updating any of its dependencies? There were changes downstream that went along with this release (paper-ripple is now created on demand). I think that if you do bower install inside of your element, everything should be up to date again :)
(please re-open if updating the dependencies didn't fix this)
I can't see ripple effect in version 1.0.4. It seems that some code
<paper-ripple id="ink" class="circle" center></paper-ripple>doesn't present in DOM module
