Screenshot of corrupted buttons

causes corruption in emerald window decoration buttons.

It appears the buttons are completely transparent (show desktop background instead of title bar background).

Using git libdrm and mesa 7.7 (non-git version).

    uxa: Fix compatible_formats() for OVER
    In separating the boolean logic out into a separate function, dc6522dd,
    I reversed the sense of one particular test:
      src->format == dst->format
    The OVER optimisation is only valid if the src and dst formats match,
    but not always.
