[Chris Dumez]

Something is wrong with the FFTFrameGsteamer implementation it seems.

[Chris Dumez]

I re-introduced the GTK-specific implementation of FFTFrame::multiply() in <https://trac.webkit.org/changeset/267428> to try and be more conservative.

I could use help from a GTK person to figure out these issues if they persist since I am unable to reproduce the issue.

One difference between the GTK and the Mac implementation is that FFTFrame::multiply() does this on Mac but not on GTK:
    // Multiply the packed DC/nyquist component
    realP1[0] = real0 * realP2[0];
    imagP1[0] = imag0 * imagP2[0];

[Chris Dumez]

Would anyone be able to try to following change to see if it helps?
