#11486: Half Float EXR with PIZ compression decode with artifacts
-------------------------------------+-------------------------------------
Reporter: groucho86 | Type: defect
Status: new | Priority: normal
Component: avcodec | Version: 7.1
Keywords: piz exr | Blocked By:
decode_block |
Blocking: | Reproduced by developer: 0

-------------------------------------+-------------------------------------
Summary of the bug:
Certain 16bit EXRs with PIZ compression are decoded with horizontal black
lines.
Uncompressed and ZIP1 versions of this EXR work fine. I have tried re-
compressing PIZ via Resolve, Baselight and OpenImageIO -- the artifact
remains.
How to reproduce:
