User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20171007100142

Steps to reproduce:

Enable WebRender:

turn on gfx.webrender.enabled
turn on gfx.webrendest.enabled
turn on gfx.webrender.layers-free
turn on gfx.webrender.blob-images
turn on layers.acceleration.force-enabled

1. Navigate to: https://twitter.com/search?f=users&q=firefox&src=typd


Actual results:

Notice that the round "follow" buttons on this page look like there are lines inside them.


Expected results:

Lines do not appear with WR off. This should look like it does when WebRender is not on.
