User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20171015100127

Steps to reproduce:

Enable:

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 any page where the title is longer than what will fit into a tab. cnn.com works
2. Look at tab


Actual results:

The fade-out effect near the close icon for the active tab is a bright white color.


Expected results:

The fade-out effect should disappear into the tab background color, not be brighter than the tab background. 

See screenshot comparing webrender vs. standard nightly.
