Bug 1160884 is probably at fault here, right? (I'm sorry if this is already being investigated, as that bug is closed)

It seems this fixed the regression on Mac 64-bit and Firefox OS, but regressed even more on Mac 32-bit and shell on Win 8 32-bit.

Note: all regressions that were getting tracked on AWFY are now reported as fixed. The guassian-blur improved a lot by a backtracking fix.
