Bypass mode creates artefacts in image

[isenkyr]

When i use openJpeg with bypass mode then i get image with artefacts. I attach input image and conversion parameters which i use to conversion. OpenJpeg version 2.1.2

-I -r 754.256332343635,542.252778413158,389.838391920622,280.264072154672,201.488493100272,144.85485970322,104.139596543597,74.8684275452172,53.8246894469852,38.6958466880406,27.8193625692756,20 -c [256,256],[256,256],[128,128],[128,128],[128,128],[128,128] -p RPCL -n 6 -t 1024,1024 -b 64,64 -SOP -EPH -M 1

Isn't it a duplicate of #674 ?

@isenkyr if you would like to encode in BYPASS mode without artifacts, you can check out Grok codec

Your command line parameters will work unchanged, and I have verified that BYPASS works correctly in your case.
