Yes.

The changeset you mention was helpful in resolving the only pixel difference I was encountering on Mac, but it does not resolve the pixel differences I'm seeing on Linux.

No, it doesn't help. I tried all 4 combinations of including/removing each of the two calls to colorMask() and the results are the same in each case.
