Open the attached SVG in a filters-enabled build of Safari, hold down Cmd-R.

The smaller it is, the more likely it happens (I can't repro with the filter applied to a 500x500 rect, I can often repro on a 50x50, and I can repro almost every time with a 10x10 -- in the testcase, I'm transform'ing up a small one and it happens a lot).

Images of what I'm seeing attached; I expect to see *nothing* (which matches Firefox and Opera).
