I reworked the flush and was happy that I couldn't see the corruption return
and that x11perf improved here.

    sna/gen5: Rework the flush after blend state changes

    QA complained that the full flush to memory was too much of a
    performance hit, so let's try a lighter weight non-stalling pipe flush
    without.

Can you please remeasure and see what the current perf hit is?
