Comment:

 Ive tried -compression_level 0, ive tried to checkout {{{3cfd4df8^}}}, ive
 tried to revert it, none of these work, the image is always gray with
 variing color corruption.
 forcing yuv422p10le produces a solid green image with versions both before
 and after 3cfd4df8
 Please someone provide a reproduceable testcase that shows that this is a
 regression. Also which version of libopenjpeg is that ?
