    sna/gen5: Flush the render cache between operations
    
    When we change the blend mode between operations, it appears that we
    must flush the render cache or else we risk render corruption. This is
    usually noticeable in rendering of single glyphs.
    
    This was originally fixed for bug 51422, but was reintroduced by
    commit 37eb7343be1aeeb90a860096756603a577df1a77

    and the desire to reduce the impact of this w/a.
