T'is a driver bug, either use the much, much faster SNA acceleration method or
apply commit 0a43d425670b883b04565296c0510e7ba03ba6de

    uxa: Implement glyphs-to-dst to avoid fallbacks

    An earlier version was buggy and introduced corruption as it failed to
    fallback gracefully with ComponentAlpha glpyhs. This is a much simpler
    implementation that composites each glyph individually, leaving it to the
    backend to optimise away state changes. It should still be many times
    faster than incurring the fallback...
