Details

In bug 1683980 we have a primitive rect that sometimes creates a very specific set of coordinates after running the vertex shader that can cause problems with clipping. It's not quite certain from the fuzzer setup how this quad is being generated, but we are sure what coordinates on output from the vertex shader are causing it. It would be nice if there were some way in a wrench test to just inject these specific quad coordinates. I don't believe the WebRender API currently supports pushing primitive item that can do something like this. It would be nice if the WR API and Wrench supported this...
