Jeff or Kyle,
Are there automated tests to prevent these regressions? I take it this will be fixed upstream too?
On my laptop with Intel(R) HD Graphics 4000
43.0.1: Pass
46.0a1 (2015-12-18): Fail
On my Linux laptop, nightly is also failing this test. Updated platform.
OS: Windows → All
This is the only outstanding failure for my test machines.
